When I try to get into a multiplayer game, the game loads and stays in WAITING FOR OTHER PLAYER. Then, the game attempts to enter but takes me out with a sign saying "You have been disconnected from Call of Duty servers". The same happens in zombies mode and playing against bots in the multi. It works just fine playing solo in zombie mode, but if it implies playing online, it doesn't work for me.

Hello there... I tried to do so but it didn't work, is there anything else that might work?
