Re: Sims 3 owned before EA app
@W0ND3RSS If your packs were originally registered to a different EA account, you won't be able to add them to this one. You'd need to recover the old account, which means you'd probably need to contact EA customer support for help. You could take a photo for each pack showing the disc, its case, and the product code (clearly readable) and upload those when you submit the help request.

If you prefer, you can contact EA Help on Twitter or Facebook instead.
The other alternative is to install your game using the discs and skip the EA App entirely. This will only work if your base game disc was manufactured before September 2012, so check the copyright date in the fine print on the back. Newer discs, those that were made to require Origin, will have an Origin logo on them as well.
If you do in fact have an old-enough base game disc and want help with the process of installing, let me know.
