I think I've been given an EU PS3 pre-order code and I need an NA one, but I don't know if that's actually the case or anything. My PS3 Just keeps saying "code incorrect or no longer valid" when I try to put it in. And the email that sent the code is from eu.square-enix. How do I tell if I did get the EU code and not the NA code, and how do I fix it?
