I work in SketchUp daily and have never run across this error before. Today I got to work and opened SketchUp normally. As of about 20 minutes ago I am not able to use it, having experienced some sort of subscription server error.
I was running fine, with a couple different files open. I opened a texture library file that I have saved, and received the usual Login window you get periodically. However when I logged in I recieved a “Internal Management Service” error, and was unable to open any file beyond that point as it now said license was invalid.
I restarted my PC and attempted the login again and got a “Server Response is Invalid” error and now nothing sketchup related is working. I have submitted a ticket to customer support but wanted to check and see if anyone else had ever, or is currently experiencing issues with their own licenses.
