  1. You may need to contact valve/steam support and explain to them what has happened.
  2. You don't need to install the game from the disk or enter the product key.
    Just install steam and login.
    Library -> Left 4 Dead -> Install.

    +1 steam only takes one time to register a retail game, after that it's attached to your account permanently.
  4. Easier (to not wait for DL): Download & install Steam, log in to your account and place disc in drive. Install from disc (shouldn't ask you for CD key again) and just update as needed.
