I have 2 PSN accounts, my original which has FF7 and FF8 and another second one under a different email and debit card which I've just bought FF9 with. FF7 and FF9 have been installed onto my PSP and I am currently logged into my original account. My psp won't let me play FF9 and also won't let me sign into my other account to let me play it, what can I do? Please help!!!
