I have a copy of FFXIV AAR on PC my sister in the other room has it on console. When she registered she did it under my SE account by accident, Today we tried to separate the account but couldn't, now we tried to buy the game again on PS3 though download, and it purchased, but is still under the same account -_-

How can she separate her account from my SE account so we can play together?!?! This is retarded complex and Mog station needs a option for this!
