No, only my desktop bundle is available. The old version is not listed in the available bundles, even though I read somewhere that it's supposed to be.
I didn't think I had to backup any files, I thought it was all supposed to happen online through my account...
Well, I have SketchUp 2015, so the plugin folder is in the users tree, which isn't supposed to create any write permission problems. I tried copying a bunch of files to the folder just to make sure, and they were copied just fine.
Also for the ruby console.. I'm not sure if I'm doing it right, but I don't get any messages...
I've recorded a sample of what happens for reference. Note that even though it is obviously edited for dramatic effect, I HAVE actually tried waiting that long.
Finally, I don't know any Gábor, and I couldn't find his name in the forums. Could you contact him for me? Thanks.
