this is why you pay 10 extra dollars for used copies of EA games.
Hi PS3 Ghosts,
If you've been unable to get past the start screen on the PS3, the issue appears to be correlated to he login process.
Here is the suggested work around you can until this issue is fixed. We hope to have it resolved tomorrow some time.
1.Disconnect the PS3 from the internet (unplug it, etc.)
2.Boot the game and progress through the start screen.
3.Once you access the main menu, reconnect to the internet.
You should be able to play normally as long as you don't return to the start screen. We'll let you know when this problem is permanently fixed.
