Heya guys, my cousin is having an issue maybe someone in the community can help with.

He just bought the game download from the Official SE site here:
http://store.na.square-enix.com/store/sqenixus/en_US/pd/productID.241996400

He has set up his SE ID and payment options, but he can't find anywhere it gave him the product key that he needs to activate the game. Is there anyone with experience in the official download process that can shed some light on his situation?

Thanks!
