Call of Duty: Modern Warfare 2 - Multiplayer “Fetching Online Profile” Loop

How is this still happening!? I uninstalled the entire game, installed it piece by piece. It started 5 days ago! This needs to be rectified. Who else is having this problem? Its not my account, DMZ works so does vanguard. #callofduty #mw2 #modernwarfare2 #dmz #dmzmode #infinity #infinityward #cod #activision
