Why am I receiving a duplicate product code error when attempting to register the key?
This error indicates that the key you are registering has already been tied to a Steam account. It cannot be registered again.

If you think that you have previously registered this key to a Steam account, please use Steam Help Site to retrieve your lost Steam account.

If you are sure that you have never registered this key successfully, you will want to contact the retailer where the game was purchased to obtain a new copy of the game.

If the retailer is unable or unwilling to assist you, contact the game's publisher for further assistance.
