Re: I uninstalled my Sims 4, and now all my packs are gone!
@Dj_Dolar_Jr You don't need to use the codes again, and they can only be used once anyway. Just open the EA App and sign into whichever account you used when you originally registered this content, and your game and packs should be available to download. You don't need to use the CDs either, and in fact it's best not to since you'd just need to update the game through the EA App anyway.
The discs are old enough that they wouldn't have any data on them about the EA App, which is why they're asking for Origin.
