Can confirm that the file I was most recently having crashing issues in AC27, I opened in AC28 and was able to delete the Zone Categories without issue.

FYI, I sent in a support request, "license delivery team" is looking into it. They did give me a 7-day emergency license in the meantime.

I also have software key and it still says no license and to launch License Manager, which I do, I log in, it shows my license on this key is up to date and that I have Archicad Full USA Subscription Commercial License, it does not say anything about...
