Sigh, I am experiencing the same issue.
It works when I use my PS3 controller only, but the second I hit a key on the keyboard it crashes.
I did step away from the PC a few minutes and when I came back the game had crashed, I don't know if it just crashed by itself or if I by accident hit a keyboard button when I put down the PS3 controller.
Either way, totally annoying.
