So, a couple years ago I bought Kingdom Hearts: Birth by Sleep. I'm trying to get more involved with my accounts now. There's a product key I can enter which not only adds it to my account, but also provides me a free exclusive PSP theme. Code page still in the case when I got it.

I could never redeem it and it said the theme was for a limited time only, so I'm guessing the time just passed. Would like to have it in my product list though, theme neither here nor there. Someone I can contact for that?
