Hello, I have a problem with my game.. Once it changes a map it shows me a black screen and an error that this map does not exist. How can I fix this problem?

It sounds like you're trying to play a single player Mao but only have MP files.

Tell me which maps you need and I can likely get the .ffs for you, I had to download them yesterday.

they are mainly maps from CoD4

google alteriwnet dlc

You don't have the DLCs, do what digitz said. Google alterIWnet DLC Repository.

Thnak you for your help. You are a great community
