What the hell? Why did you revoke my key? Anyone else having an issue?

Apparently there's something wrong with my copy of SZ. I've ♥♥♥♥♥♥ through a few levels, had to take a break. When I went to play today, it just hung at the intro logo with the closed metal door and sat there for 5 minutes. I ended up closing out the gamethrough the task manager. Anyone else had glitches like this?...

I downlaod it , and it just launches the game? shouldn't take 15 minutes to install a soundtrack, lol - the game doesn't even take that long./ Also watching tthe credits at the title screen seems to count as beating the game, and opens up Super play mode. ( All this time and the soundtrack still hasn't downloaded, steam DLC manager thingy says 0/1 installed - and it's " downloading " ) ...

Bonjour, la manette pro switch n'est pas reconnu dans le jeu "the detected controller is unknown. It is recommanded that you remap the controls in the options menu." et je n'arrive pas à assigner les actions à des touches de la manette. La manette est bien reconnu dans steam. Merci d'avance....
