Today I purchased COD4 for my uMBP and it had been running just fine, It was finding lobbies and starting matches without any problems, but then I went to .com to download a patch for the game. After I updated it, I restarted the multiplayer and Now I can't Find any lobbies at all. Before there were about 60-70 now there are ZERO...what is my problem?Oh, and I reinstalled the game but it was still not finding any...Any Help is appreciated!
