I sent an email to them and got a new key within 20 minutes, which worked fine.
mmoga aren't looking very good out of this.
Well! I just bought a key myself for the fun of it and it was used! Go figure :D Must be selling same keys multiple times then :/
Get lucky??? it's a 28 character alphanumerical key! XD
it's hit and miss really. I had same issue with fanatical where I had used up keys in a bundle, got sent new ones no problem. They either sell same keys more than once or people just get lucky inputting keys and redeeming games ;)
