So, yesterday, the day before that and the day before that, (When I bought WaW) I could find servers easy, Multiplayer MUCH more so, but I could fairly easy find a zombies game every so often, and they showed up, but I ran a mod today, "Aliendefense" and ever since i ran it, I can not find ANY servers, whatsoever, no multiplayer (There were tons) and no zombies, at ALL... does anyone know how I can fix this? does the game think I cheated?

Hello! I was wondering if anybody wanted to play some custom zombies with me I have Malibu Drive, Cheese Cube Unlimited, Nacht Der Untoten Reimagined, ( I Can use Realism ) SuperMario, and Aliendefense!

On the side note, why are there so few people lately? I have barely seen anyone playing it, and if they are they are either in a Private Lobby or I can't join them for some odd reason
