I think so? That's where I went wrong. Did she use the registration form on the PS4 or via the pc? When she starts the game and logs in, does she get any errors? There should be a code on the back of the booklet to put into psn as well. I can't remember but I think you have to go through the profile page on mogstation/se account site and then there will be a "activate/link psn account" option there somewhere?
