I got a new computer and want to use my world bundle and all the other stuff that comes with the games to I payed for them so I don't see why I can use them on my new computer and I need codes for two games I have but lost the books for them please help ?!?!
@blake4912 You would have redeemed the codes when you first received them either on Origin or on the Sims 3 website. Could you try installing Origin client, logging in with that same account you used to redeem the codes and check if the base game shows in the client?
Now the base game and expansions can be downloaded from Origin, but worlds have to be downloaded for the Sims 3 website after logging in. I would recommend using your Purchase History for that: http://store.thesims3.com/purchaseHistory.html
Let us know how you get on!
