I get this virtually every single time I try to connect to a game on COD5... It's reallyyyyyyyyyyyyyyyyyyyyyyyyyyy getting on my nerves... BADLY!!
I'll stick to Battlefield until I figure out why it's doing it... I think it's something on my side. Also, when I try to chat with people outside of a game, it doesn't work, I get errors. But my headset works during gaming... so it's got me confused... Any Port Forwarding that's supposed to be done?
