I've been playing this game since launch and haven't had a single problem until now.
I was just running through The Black Shroud and the game crashed on me. No reason given, just a "Such and such has crashed. Windows is trying to figure out a solution to the problem"
Now it will either crash the second I hit play on the launcher, or after I select my character.
I have no idea what is going on with this. I can't get in at all now :\
