Question
I just found out that I linked the wrong Xbox LIVE® Gamertag/PLAYSTATION® Network to my Rockstar Games Social Club account. Can I change it?
Answer
Yes. Due to the way accounts are linked through Xbox LIVE® and the PLAYSTATION® Network, you may only have one account linked at any time, but you can also change it at any time.
When logged in, to the Social Club click the "Profile" button and then click the "Account Linking" tab on the left-hand side of the web page.
