I can get to the dungeon when you start at the very beginning, and then a few seconds later, it'll crash. Any solutions? I use Windows 7 x64. Phenom II x4 955, Raedon HD 5770. Previously, I couldn't run it (about a year ago), a few days ago, I reformatted the PC completely and tried again today after redownloading the game, and it's the same problem.
