This error is very unexpected.
As SketchUp starts it loads from your Plugins folder the ../SketchUcation.rb file to set up the rest of the code.
This in turn loads ../SketchUcation/SCF_loader.rbe
Which makes the toolbars, menus etc, and loads the various other code files needed to work the extension.
It's failing at the loader's line#193 with the NameError uninitialized constant SCF::TOOLBARTOGGLEup
This is one of many Constants set up to set the text for the toolbar button's tool-tips etc.
Because earlier lines of code have already set 27 similar Constants like SCF::TOOLBARTOGGLE, without any errors I can't immediately see what might be causing this issue for you. These Constants are read in from a text file shipped with the set - ../Strings/SCF-EN-US.strings
I've checked them and the correct file is included in the file set archive 5.0.4
Since the TOOLBARTOGGLEup Constant was just added in for this revision, then it looks like you might have a earlier version of the strings file [e.g. <=5.0.3], that the needed newer 5.0.4 l, and the loadedr is then tripping up later as that particular Constant hasn't been defined.

How did you install the newest version ? From the ExtensionStore dialog, or from a downloaded RBZ - if that. then how did you install the files/folders ? Using the Native Extension Manager's Install function should copy all over and overwrite any preexisting files etc - which it clearly has for the loader etc; or did you manually copy the RBZ's contents into your Plugins folder ? If you did that then maybe you inadvertently skipped the new strings file version ?
You can see if the existing installation for ../Strings/SCF-EN-US.strings is correct by opening it with Notepad++.exe and around line#31 TOOLBARTOGGLEup= .. defines the Constant. If it's there then something is weirdly adrift, as your other files aren't loading it: but I suggest that it will almost certainly be an older version with that liine missing.
If it is missing something when wrong with the installation - probably skipped that file's newer version etc - if so the some other files might also be suspect.
Please try SketchUp's Extension Manager Install function again and pick the 5.0.4 RBZ . After it installs that, then restart SketchUp and see if the error recurs...
Alternatively you can use a manual way - close SketchUp, then extract the RBZ's contents using 7-Zip or similar [an RBZ is a renamed ZIP file], then manually copy all of its contents - i.e. parts 1) the SketchUcation.rb file and 2) the subfolder SketchUcation [and of course all of that folder's contents intact - files and subfolders of more files etc. When prompted choose to Replace the 118 or so existing files [never Skip them]. Afterwards restart SketchUp to sync everything and see what happens...
Please let us know what happens...

With the latest versions of the SketchUcation tools installed you should see the options on our web page or in one of the settings tabs in the ExtensionStore dialog ?
If not Rich will probably be able to do something via admin...

You can't do that in one step. Do this.
Use the Tape-measure tool to make the first at 1/2" as before click to confirm, Select the guide line, and chose the Move tool, press Ctrl to invoke Copying, make the copy off 1/2" and immediately type 9x press Enter to confirm.
Now you have 10 guides at 1/2" spacing.
You can make multiple offset copies of selected things, including guides, but you can use the Tape-measure tool to make more that one guide at a time.
You can also make radial copies at set angles using Rotate + Ctrl for Copy and entering the number needed, press enter.
It's probably best that when inputting lengths or angles to the use 9x rather than x9 as the leading letter might sometimes get confused with ab x shortcut.
To make guide copies at a set spacing, e.g. use 9x but if you want to divide between a start and end guide manually pick the start and the final one and use 9/ to divide - that way you don't need the exact dimension, but can be sure the spacings are all equal.

I'll look at it for you and send a fixed version by PM - it might be early next week...

@Gábor needs to look at his server-side coding.
I expect the user-side would always be sending a list of all installed extensions and their versions, Gábor then checks if that user, on that computer, in that SUp version has previously installed any extension[s] in the current version available in the ExtensionStore, and if not it should advise that there's an update available, and list it on the appropriate page to auto-install...

Get v5.0.4 and install it, you can do that using the current v5.0.3 dialog, rather that via a download RBZ.
But why not try reinstalling LibFredo6 15.6a 'automatically' from the ExtensionStore dialog's main page.
Then after a SketchUp restart the update-available message should stop.
Incidentally, why do you think it's that LibFredo6 extension ? Is it the only one you installed 'manually' from a downloaded RBZ ? Why did you do that ? It appears that you might have confused the records server-side to think you still need to auto-install it for its records...
Thinking farther - aren't you seeing a update-available reminder for v5.0.4 itself in the v5.0.3 dialog ? Are you restarting SketchUp so that you get a refreshed set of data after any major extension change ??

I tried it with my very old ImageTrimmer, and it took a very very long time !
Then I tried it with Fredo6's new https://sketchucation.com/pluginstore?pln=Pic2Shape
It took 25 minutes, and I had to manually hide the edges and stand it up, but it worked well. Here's the SKP v2026... trimmed.skp

The SKP file fails to open with a file-type error, but looking into its contents shows a v23 file and not lines of 0s , unlike a lot of files with that error.

Die SKP-Datei lässt sich aufgrund eines Dateitypfehlers nicht öffnen, aber ein Blick in ihren Inhalt zeigt eine v23-Datei und nicht Zeilen voller Nullen, im Gegensatz zu vielen anderen Dateien, bei denen dieser Fehler auftritt.

SketchUp Model૿{23.0.419}

So it's FUBAR.
Perhaps someone else has other ideas...

Es ist also komplett ruiniert.
Vielleicht hat ja jemand anderes noch andere Ideen …

The red dot on the toolbar button shows shows that updates are available.
If updates are available then the toolbar shows up by default even if you have closed it previously. This is to ensure you see the availability.
However there are two options in the Extensions > SketchUcation submenu, covering the toolbar close/open status. The first is the same as opening/closing the toolbar manually with the update-availability auto-opening it later if appropriate, but the second one let's you close it and then ignore update alerts, it you choose that you need to manually check for updates by opening the toolbar or ExtensionStore dialog.

@fizaharon
LibFredo6 doesn't need a license.
What's the message about ?
Are you using an extensions that needs a license and it's reporting the trial period has expired ?
If so license it, or continue this report in that extension's forum-thread, not here.

As well as your computer-name, your windows-username shouldn't contain any non-ASCII characters.
Because these can trip up Ruby code processes...
Also you do need to restart your computer after the renaming...

Your PNG processed fine for me.
Although there are a lot of semi-transparent pixels that could be improved by editing the image [Gimp].
I flattened the image which remove all transparency, then I selected all of the 'teal' background pixels with the magic-wand, and deleted them... and finally added the alpha channel back in. This takes longer to process, but it gives a much better result. Also cropping the image to avoid bothering with all of the background you don't want anyway speeds things up.

We are a bit under informed...
If you post the actual tree PNG image it might help resolve this...

This works in all newer versions of SketchUp.

This is explained under its 'More Info' link...
https://community.sketchucation.com/topic/117065/plugin-edge-tools
Its entry appears under the Tools menu.
It also has its own Toolbar, that can be activated.
It also needs TT_Lib2 installing.
After the installations of these restart Sketchup to sync everything...
Run it with the Ruby Console open to see if there are any errors...

@bebert77
Please give us more info.
Error messages / dialogs etc...

@alskaro
You can already do that to a section cut face group.
Unlock it [if needed], then edit the group, and apply the different materials you want to the faces.
If you regenerate the section cut face then those changes are lost.

@Jspro
If you read the extension's 'more info' link in the PluginStore you will see it works as far back as v8 !
So the answer is yes.

I think not.
Try out some permutations and see what's best for you...

Find your version's Plugins folder.
Open it.
Extract the contents of the RBZ [ZIP] for the extension/plugin.
The resultant folder should contain a .RB file, and possibly a subfolder of the same name.
Copy the .RB file and subfolder into your Plugins folder.
Restart SketchUp to load the .RB file... follow the instructions on the extension's usage...
