so i bought a copy of ffxiv for ps3 for the gf to play. when i installed the game i used the registration code under my ps3 id thinking it wouldn't matter after install. now she wants to play it on her ps3 user for the trophies n stuff but it wont let us. when we try to use the code again it says its not longer valid. is there a way to transfer the code to the correct ps3 id?
