Re: Can't link my PSN account with Origin
Usually whenever you play an EA title on a console, it creates an Origin account for you automatically. It's possible that you may already have an Origin account linked to your PSN, which is why it won't let you link it to the Origin account that you want.
Here's an article that should explain it a little better: http://help.ea.com/ca/article/linking-your-gamertag-psn-id-or-ea-classic-screen-name/
If you need help getting all of your Origin accounts linked up, you can contact a game advisor here: help.ea.com/en/contact-us/new/
