Authorisation Code for Kingdoms of Amalur Reckoning

[Demonhunter706]

I have not played my game in a couple of months. Today I went to play it and had to reenter my Authorisation Code.  It would not accept it telling me "the code has already been used.  How do I solve this issue so I can continue playing my game?

Thanks

Doug
