It's either a disc error or server error.

I have your solution jonny41177 reboot the game and sign out of the playstation network first. So when the game boots you are not logged into your PSN account. Once you get to the first load screen it will ask you do you want to sign in? Select yes. You will then be prompted with the online user agreement forum that you never saw when you first got the game. I just found that solution and I am sharing it with everyone. Your problems of the semi frozen game are over. I had them for a week and was wrecking my nerves trying to figure it out.
