How to play COD4 MP
Posted: Thu May 29, 2008 11:34 pmI tried 5 serials and none of them work, i want to play online 
Well most of the serials that are Out to public are PB detected, and they
cant be used on PB servers..
So what u do is...
JUST PLAY IN NON PB SERVERS
also many plaiers are plaing in the servers ... having the same Key as you..
So just try again later..or search for a server that does not have the same key as you......
It will drive you mad until u get a a server that there are no1 with the same key as you...
