I recently reformatted my ps3 n now when i go to play on MW2 it wont allow it to load.
Registration of the trophy information could not be completed. The game will quit.
Anybody any ideas. I have tried creating another username but it does not work. Please help i am missing my COD play.
check your game data and if there's a MW2 game data file delete it then reinstall.
