Re: Origin is telling me my activation code has already been used and i cant download it for the sims 3
@emzy190516 What exactly has happened? It would be useful to know precisely what you're experiencing right now, as your comment could refer to several different relatively common issues.
If you already registered your codes to an account sometime before now, you don't need to do so again, and in fact Origin will not allow the codes to be registered more than once, even to the same account. So if you want to redownload the game, you need to use the same account to which the codes are registered.
Sometimes, Origin itself can act up and not recognize that you own particular packs, even when you do. You can try to clear Origin's cache, or even uninstall and reinstall Origin only—this will not affect your installed games.
If you can't remember your password for the original account, there should be a way to reset it. If you can't remember your username, you should contact EA customer support. Someone there can help you reset your account details. Click on the "Help Center" link at the bottom of the page and select the options that fit your problem.
If you never registered the codes but believe that you're the original owner of the games, contact EA with as much proof of purchase as you can find (receipts, email confirmation, if you have discs then photos of the discs, cases, inserts and jackets might be helpful). There's no guarantee, but an advisor may be willing to issue you new codes so that you can download the game from Origin.
If you bought the games secondhand, then you're probably out of luck. Unfortunately, EA does not allow transfer of ownership of a game or pack from one account to another.
