Hey, Until recently I was only running official firmware on one of my PSPs. I had legitimately purchased several games from the Playstation Store, including many PS1 Classics. A couple of months ago I 'hacked' this PSP and am now running the 5.50 Prome-3 firmware. Since doing this, the legit games stopped working. I've tried everything I can think of. I've deleted them from my memory card and copied them over from my PS3 again. I've deleted them from my PS3 and re-downloaded them and copied them over again, nothing worked. I just keep getting the same CA000005 error, and a message saying the game could not be started. This is a real pain in the ass for me. Does anyone have a solution or am I just going to have to pirate all the games I've already paid for? Cheers!
