I had the same thing, starting MP3 and it just crashes, I verified the integrety of game cache, next what happens is I can't get past prologue because it does not what it should do.
Verified again, and this time everything works.
I personally had to verify the integrety twice for my Max Pain 3 to work like it should.
using the steam version ofcourse.
did this, also updated driver for card, not sure which did it, but now its working, no crashes whatsoever
