Hi! Is there a way to check what devices are authorized for a classic licence? Trimble account is showing only sketchup free as my ‘licence’, my Classic 2021 Pro licence isn’t there. I started having problems with my licence since changing my internet provider (on my PC). Every time I opened Sketchup it would say there’s a problem; had to add my licence again and again. And today the same, but this time I got a message that too many devices are using my licence. Couldn’t even start Sketchup. After reading a little bit about licencing, I got the idea to delete a licence from my old laptop - that I have not been using for years. But still, I have only those two devices that sketchup was ever installed or used on. Is there a way to check what is happening? And/or deauthorize all the devices using my licence? ---
