Hello! When I End DLC "Dead Money" and I Want back on the Wasteland my game is crash. I have loading to Mojave Desert, and I have Black screen.
I record a film. Please Check this: http://www.youtube.com/watch?v=eWTGz1Ln8wQ
I really want play!
Sorry for my bad english, hehe

I don't know the answer but I would try unequiping any items you picked up during Dead Money (the Assassin Armor, the Sierra Madre armor, any weapons, etc) then go back. You shouldn't need to drop them, just unequip them. This may not help at all, but it's worth a shot considering they suggest the reason some people have problems with getting into the DLC in the first place is because they're wearing quest items. Basically, go back naked, carrying nothing.
