I don't know what it is, but when i start up the multiplayer in Black Ops and get in a lobby, it always says game lobby closed. I havn't been able to join any games. I tried again multiple times with the same message popping up, "Game Lobby Closed" I don't know if this has something to do with my router or what. Right now, it's annoying me that I can even join one game without getting the "Game Lobby Closed" message, or even "Lost Connection to Host." If someone can tell me if I need to configure the router please do. This has never happened before for Black Ops. Thank You.
