Plutonium

I found the solution, if you have Gamefirst VI installed, uninstall it!!!
It prevents people from loading into the game and also effects games like BO2 and so on

Every single time I connect to any server on IW5 I keep getting stuck on the part of the loading screen called "Setting up game", and in the console I get these messages ;
Hitch warning: 5320 msec frame time
Downloading avatar for client 11...
Downloading avatar for client 0...

This doesn't happen for private matches, only on the server browser.
Has anybody ran into this problem beforehand, if so, how did you fix it?
