If you buy your game from Origin, you don't have to register it anymore. Read more about it here:
thats not what im asking, i need to redeem the code before i can use the game, because the game doesn't show up in either origin or the sims 3 website but for some reason my both origin and the sims 3 website say my code has been used but i haven't even downloaded the game yet...seen as it is a store item and not an expansion pack i need the code to redeem it
every time i put my code in it says this
'The code you entered has already been used. Please check the code entered and try again. If you continue to receive this error it may be that the code has already been applied. If you need further assistance, please go to Contact Us.'
