How to fix the ps3 modern warfare 2 problem of multiplayer? It gets stuck at updaing rank and unlocks?

It could be from lack of memory space on your PS3 if you have tons of demo's, Music, Videos or anything else you really don't need anymore just delete them. Try then, If still not working then you will need to send a problem report to Infinity Ward.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
