Bought the game today for my son, Spend a few hours attmepting to get it to work eneded up going and just getting a gift card from the shops in order to buy the game for him.

used that now the game isnt allowing him to play the full game only the Demo. he is very upset because im unable to give him the game he has attmepted to play the demo but all he wants is the creative.

Also attempted to log in with his Xbox live account and that still didnt work. hes xbox live account is the same as this account.

Any advice or fix would be amazing
