I've been using your software for years and I love it. I'm just a hobbyist who owns a 3D printer and your program has been a great tool, thank you. Upgrade to V4 was great and it has been a great experience even compared to other software that you can use for free like fusion 360 which I've been trying to avoid even though the other 99% of the hobbyists use it while I told them DSM is better (and it is)... I tried V5 beta and it was cool but I kept using V4 waiting for the stable version. Then you released the "stable" version and... Oh hell, what can I say?. Now I can't log in cause I get the message "reached maximum number of installations" so I go to my profile to try to deactivate any other installation and that''s not even an option. I created another account so I could use the software and after a while I get the message that "DSM can't be upgraded blah blah blah" and the program blocks itself -even though you already said you fixed this on the server side-. Now it seems I lost a project in which I've been working for weeks and I made the mistake to open and save in the new V5 "stable" release.
