Didn't they send it to your email?
Maybe you should look from trash can/deleted, since emails sometimes get automatically deleted by the spam filters.

Mm, thank you. Seeing as I'm still 15(just one month away from 16, though), my dad is the one who bought the game, thus he is the one who got the e-mail, not me. I got to it this morning, so I will enjoy my game now. Thank you!
