No matter the class, because I tried two and they both caused game to do an "unexpected crash" during the first opening road fight. I hit the first monster once, as demon hunter and warrior and the game just suddenly crashes. I have now spent some time going over the forums trying to figure out how to fix this and have come up with nothing.

Windows 7 64bit
i7 2600K
GTX 560

I don't know what else I need to put on there. Game loads fine, lets me select class fine, just as soon as I begin traveling on road and hit anything, it just crashes.
