Sims 3 nothing works that is from store and exchange

Ghiby​  I don't know whether the saves are corrupted, or how they would have become so.  But testing on my end could be informative.  So feel free to send me one or more of them any time.

If you do still have the CDs, and your base game copy was manufactured prior to September 2012, you could install the game via disc and do without the EA App entirely.  Let me know if you're interested and need help with the process.

I really don't know anything about your other games, so I can't help there.
