I just bought a new ps3 and created a new online account? And the first game I put in the ps3 was call of duty 4 and played some campaign but then decided to play multiplayer online? So when I joined a lobby everything was going okay for a while but then something popped up on the screen It said I ranked up to the five star symbol level 55 and all the guns were unlocked which was weird? So then I deleted the entire game to start all over from rank one? But it did the same thing as soon as I installed the game on the ps3 and then went to multiplayer again I was still on level 55? Wasnt it suppose to delete that is what I dont understand? Can someone tell me how to fix this its only on multiplayer online?
