Hi. I won the giveaway, tried to activate the key but it says:
"Sorry, but this product is not available for purchase in this country. Your product key has not been redeemed."
The game is not blocked on my country (argentina), it's available for buying on the store. The key maybe have some region lock, I dunno.

Edit: if you want to reroll so other user can win the key, go on, I can't do anything with that key anyways. It's still usable, but not for me.

Y'ello! I'm leaving a new comment to ask you for a reroll, so I don't have to mark it as "not received" and someone else can win the game.
You just need to submit a ticket on "Support". Thanks.
