Hey Buddy, thanks for the win. Turns out I already had this game. Please re-roll.

Cant redeem the key. Duplicate product code.
What should i do? already click retrieve account button.

Key is not working. i dont own the game i think since its not on my library. you can check my profile if you dont believe me.
here the message:
"Duplicate Product Code. The product code you've entered has already been activated by a different Steam Account ..."
