What particular promotion are you trying to participate in? If I were to hazard a guess to your particular problem, it would be:
What you got in the box was NOT a game-key to redeem with Ubisoft's uPlay. What you got was a coupon-code that you need to redeem on the appropriate Never Settle: Reloaded, or Never Settle: Forever page (depending upon the promotion you bought the card under). Redeem the coupon-code for the actual game-keys that come in an e-mail to you. Then take the game-key in the e-mail to uPlay.
That's just a guess, however. I need to know the particular promotion you bought into to help further.
