My PSN ID is linked to the wrong account and it won't let me change it at all to my actual account. Basically when the ARR beta started I played on the PC and the missus played on the PS3 but she tied her account to my PSN ID so now if I try to login to this beta on the PS4 it already has her SE ID in the box and won't let me change it to mine.

Is there any way to remove her account from my PSN ID so I can use my actual account with the PS4?
