It's really not rocket science.
Have you read the licensing guide ?
You seem to be making something from nothing !
Try this...
Download your license file and store it somewhere safe on your computer.
Open Sketchup and find the extension you have now got a license for [usually under its own submenu under Tools].
In that extension's submenu there's a 'license' sub-item.
Use that which will open a dialog.
Validate its license by clicking the appropriate button...
Then find the saved license file and validate it.
From there on your extension should be licensed...
You can do this for up to three licenses on used different computers...
A few steps to do it properly [once]...
Did so "properly once" and have used it repeatedly in the past. And yet this error message popped up once again when I went to use the tool. Hopefully it remains stable this time and I don't have to waste time messing around with licensing.
