The only solution is to create a new adult account through family manager. Unfortunately, he or she will lose any progress as it is a new account. I mean this isn't Grand Theft Auto for Christ's sake. It's a football game. The only access they have to anything inappropriate would be through chat while going head to head. Simple solution, disable it in the settings. The error message saying you have to sign into the PlayStation network to basically sign into EA is NOT the problem. It is an age restriction issue. Never again will I create a minor account. There are so many stupid hoops to jump through like this that it is more trouble than it is worth.
