Windows 7 Product Key Upgrade link is missing

I  purchased a gateway with Windows home professional on it.  I select windows upgrade and selected Professioanl upgrade.  I downloaded it , updated the key. Its been over 30 days now and windows is coming back saying it is not  a legitimate upgrade key..  The update product key  link under systems does not appear.  Does any one have any suggestion on how to fix this.
