Im playing the Steam Version

verify ur cod waw game files on steam and after that try again then it will work

Am i the only one getting an Error when trying to run it?

Bist du in Deutschland? wenn ja dann ist es weil unser Cod waw gecuttet ist google mal cod waw uncutt um den Zombie modus zu bekommen dann müsste es gehen

Great map! i like it so much, but there is a bad thing:
The zombie spawns
The zombie spawns are very disruptive when walking, I died once from getting caught in a spawn and apart from that, everything is great! : D
