Re: Old Sims 3 expansion packs
@bella_guz33 Does your current computer run Windows or macOS? Do you still have access to any previous computer where Sims 3 was installed? If so, you might be able to find the other product codes there.
However, it sounds like you did already register most of your content. Even if you never used Origin, you might have created an account on the old Sims 3 site ( www.thesims3.com or store.thesims3.com ) and added the packs there. That site and Origin/the EA App share information, so a code used in one place would register as used in the other.
If you did have an account on that site, just sign into Origin or the EA App with the same email address and password, and your content should appear in your game library. If you don't remember what email you might have used, enter any address you still have access to on any EA site and click "Forgot your password?" If the address in question is associated with an EA account, it should receive a password-recovery email.
