Hi I upgraded to 3.03 OE-C a few months ago and all was fine until one day my son played GTA LCS UMD and since then none of my memory card games load. It comes up with a meesage " the game could not be started (80020321) I think when he started the game it loaded the crack from the firmware downgrade from 2.7 down to 1.5. I have gone back to 1.5 using the recovery utility and then back to 3.03 OE-C with no joy. Any help or ideas would be appreciated.
Thank You

I can still play UMD games and all else is fine?
