Crysis invalid key from steam

[KingSno]

I bought the Crysis pack from the steam summer sale and now it asks me for a key that i got from a game card, email, or my manual. the CD key offered by steam does not work and it refuses to let me play the game until i get a new key. i have received no emails and don't have a manual with a key in it. can someone help me? i just want to play Crysis
