Battlefield Bad Company 2 Help

I just bought Bad Company 2 today and I'm having a bit of a problem playing it. I downloaded the update, installed the game and it went to a "Synchronizing trophies" screen and it gets to 100% and just stops. The game won't go past that screen. It's not frozen because when I push the eject button the disc comes right out and I end up back at the XMB. I've tried deleting the game data and reinstalling it but that hasn't worked. I was just wondering if anyone else has had this problem and if so have you figured out how to fix it. Any help would be appriecated. Thanks ^__^
