So, i bought the actual hard disk, and upon opening it up i discovered i have no cd key. I have the manual, the fallout preorder card, the advertisemant for Skyrim/rage, and the case itself. Is there a card that i'm missing, or is the key supposed to be on one of those?

also, i have the pc version if that helps.

mine was a sticker stuck to the inside of the cd case below the disk opposite the inserts.
