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...

Use the Outliner.
You can then expanded the 'tree' and select the nested Container, and double-click it in the Outliner to edit it that way.

It's not published, buy you could try contacting its author and offer to buy it ?
See the first post in the thread...

So at the moment you have SketchUcation toolset v5.0.3 OK, the SCF licensing OK and most of Fredo's extensions OK.
BUT Fredo'sTools must be disabled for this to get everything else working.
So the issue lies with FredoTools.
Have you tried reinstalling FredoTools from a newly downloaded RBZ ?

@slbaumgartner

I meant the SUp version.
I suspect that most users will have newer SUp versions ?
The reason I cited @fredo6 is that he is instrumental in the licensing coding, and I am inviting his input...

The licensing code hasn't changed in several versions but that seems to now be causing at issue - way back to the lat v4 ?? @fredo6 ??
Other MAC users haven't reported anything... Are you still running v2019

So to clarify. Please confirm...
You now have no SketchUcation.rb or SketchUcation subfolder in your Plugins folder having temporarily moved them.
You have temporarily moved the SCFLicense subfolder and SCFLicense.rb [usually in your SketchUcation folder] back into your Plugins folder.
You have restarted SketchUp.
Does the licensing set up load ?
It seems not !
If you add the SketchUcation subfolder and its RB file back into Plugins, AND temporarily remove the SCFLicense.rb and subfolder from the SketchUcation subfolder, AND also remove those you moved into Plugins: after a restart of SketchUp does SketchUcation toolbar/submenu load OK ? If so the issue appears to lie with our licensing set up... [@fredo6 ?]

Incidentally, our test is...
[Assume a valid path to load the RB files]

require('zlib') unless defined?(Zlib)
require('zip')  unless defined?(Zip)

SketchUcation tools only loads the ZIP gem stuff if it hasn't been already loaded [required].
I suggest you adjust your code to do the same.
It doesn't break things. it just warns about it already being installed ?

Compatible with v2017 and newer [better].
You can try an older version, but no guarantees...

@jackybe67

This has been reported before.
It's probably because you have one of Chuck Vali's extensions loading.
He omitted giving it a Version [check in your Extension Manager for that omission...],.
This means that when we try to find its version so we look for updates it trips us up with a fault.
Our v5.0.3 sidesteps this very problem [amongst others] and should be published very soon...

@Macho3001
The > on the right end of the extension details, if you click it it expands the entry and shows the Version, or in the case of Instant Architecture == nothing !
The 'unsigned' message appears if an extension hasn't been processed by Trimble/SketchUp, if the extensions is older it's probably not been updated in the last few years, that's OK if it's from a trusted source and your Extension Manager's > Loading Policy is set to Unrestricted, otherwise it's loading is blocked.

I'm preparing an update to the SketchUcation tools to robustly trap for this kind of unexpected problem from poorly structure code by others...

@Macho3001

I'll look into it further...

Meanwhile:
It looks like you have an Extension loaded which doesn't report a Version in the Extension Manager - if it returns '' it ought to be OK, but with a nil it cause the trip hazard.
A known cause is some of Chuck Vali's stuff.
But the nil return was trapped for this very reason.

Can you check your Extensions and unload any without a Version set, and see it SketchUcation then loads on a restart. And let me know what Extension[s] are the culprits...

@gullfo
So this file/folder copying was an error with the v2026 extension-migration tool by SketchUp, not copying all DM's files over and causing an error ??
It has nothing to do with the SketchUcation extension - except in so far that it breaks it and stops it loading !!

@Edson

Can you please cause the error dialog again, this time click the bottom-left button to 'Copy All Errors' to your clipboard.
Then paste the full error report into a reply here.
It should tell us if DM's code is somehow messing up our files' loading...

There is no calls to a "DMLanguageHandler" directly associated with SketchUcation, so that's a mystery.
I'm wondering if it's part of the compiled @fredo6 licensing files ?
Or something else might be causing an issue which then clashes ?
I fact I can find nothing in any Plugins I use needing this [PC].
You are on a MAC running which SUp version ?
Under investigation....
