Deleting the folder in Documents worked, thanks!

Other games work fine, no software changes.

Drivers updated, mouse issue still occurs.

After managing to get into a single player game, the game is extremely laggy and almost impossible to play. Using the mouse while playing works, but after trying to exit from the game via the menu, clicking on the "suspend" button made the game to crash. Remember I was running this game perfectly fine yesterday with no lag at all.

EDIT: I also reinstalled the game, mouse bug and lag still occurs.
