Did Sony put a protector thing on new UMDs now because I've tried 6 different Ratchet Clank Size Matters ISOs and they don't work. They show that background screen thing that appears for all games before you click on it but after I selected it, it showed that PSP screen that comes up for any game, and then the screen turned black and I waited 2 minutes. I have OE 3.10 and I've tried other ISOs and they work. Can ANYBODY help fix this problem? I don't want to be limited to playing games released before a certain time.
