I have a major serious problem. This day I have played Tabletop Simulator (it worked perfectly), but when I tried to launch it a few hours later, it wouldn't start. I am stuck at the message "preparing to launch Tabletop Simulator" on Steam and it won't start or disappear. Not even an error message. I also tried to launch it from the Desktop, but without success. It just acknowledges that I tried to launch it by the loading cursor for a few milliseconds and it stops running.

I even removed Steam and the Steam-related games within, reinstalled, "redownloaded" and nothing.

I need to play TTS, I have many hours in it and the game is a purchased/gift version. What can I do? Is my copy ruined forever?

Thanks in advance!
