If you win, please activate the game pack and mark the giveaway "received" as soon as you can.
If there is an issue with the key allow me to fix it or allow for this giveaway to be deleted. Since this is a DLC make sure you don't own it before entering the giveaway / viewing the key. If you reveal the key - it is considered compromised and the giveaway will not be rerolled.
Thank you and good luck :}
