Yet another code issue...

So, I get the game and put in the code. That was how easy it was supposed to be...and yet...

I bought the game for the Xbox 360. I entered the code in the website and not the Xbox when it prompted me.

I entered the code under the email I use for my PS3.

Ouch.

My eagerness gets in the way of logic once again.

Would anyone by any chance know how I can fix this?

...please?

This issue has been resolved, thanks to Pacifien!
