Seeing as you're from Germany there is a possibility your copy is censored due to Nazi content. Can you load stock Nazi Zombie maps like Der Riese?

No i can't play any zombie maps exept custom maps i tried playing the story ( i only played the last map to get the credits for nacht) but it always crashed *spoiler* when i took the russian flag and placed it in the ground
