First of all, thank you all for your patience while our teams have worked to resolve the problems redeeming the codes and apologies once again for the inconvenience this has caused you all.
Please follow these steps to complete the registration of your game:
For players that previously received a 16 digit code in their Humble Origin Bundle and have already redeemed the code through Origin, please open the email you have received from Humble Bundle titled: “Your Humble Bundle order is ready” and access the hyper-link to view the updated 20 digit codes.
You should then redeem these codes on the Sims 3 website (Redeeming the Sims 3 base game first).
Thank you.
