Dragon Age Origins

[PennyAE1955]

Hello,

Have just purchased Dragon Age Origins CD and have tried to get the code.  I have gone through registering myself and found where to enter the code to give me the extra needed.  I have entered the code in the CD box and am told that that I am "unable to redeem code.
That code has already been used, and cannot be redeemed again."

Can someone please help.

Thanks

Penny
