So I was playing the game in fullscreen as usual, but I decided to pause and alt+tab to check what was going on in a chat room. Going back to the game, the resolution became window sized somehow? I closed the game and reopened it, but it made my computer crash. Every time I launch the game now, it's in windowed mode and it quickly makes my monitor go to black and I gotta reset my computer. It's a real bummer because I was getting really into the game. (and working towards 100%. sooo close...)

I tried the checking file integrity option to no avail. I tried reinstalling the game too. Nothing seems to be working, and I don't know what to do. Any suggestions?
