If you get the error message "can't connect to online servers" and you have tried every possible solution, you my friend are banned. Activision said so, if you contact them via there support page... i hope this clears up things with people not being able to connect but their friends can.
HAHAH, thank you for clearing that up !!! I got banned, didnt like the game anyways, might go back to black ops
Didn't like the game either, hence why i was hacking so much... lol if it was a good game like idk BF i would not of hacked, the game sucked, same gameplay as every other COD there is. (Waste of 60 bucks) No problem for clearing everything up as well.
