Dude, I need your help too.
I bought 4 of the MW3 DLC for PC, like 5 new maps 2 weeks ago.
However, I am trying a problem, just do not know if it's because of them or because they gave the Prestige.
Next, before buying or quick connected to the Prestige rooms (Play> Find Game> Standard Playlists).
Now, when I do the same thing, looking for vai ping, begins at 50> 75> 100> 125 and find no one gives FOUND IN GAME.
I can only connect one time or another going on Collection 4 Playlists, but I get a tremendous lag.
Someone can tell me what might have happened?
