Zombies crashes when starting up game

[joschi.r]

Everytime i start up zombies the game launches just fine and I can see the main menu pop up. But after one second the game just freezes and closes itself, no errorcode whatsoever.
Multiplayer on the other hand works just fine.

[joschi.r]

Any suggestions on how to fix this?
