If you installed the game on a system drive, I believe you can rollback if your windows system restore is turned on, since the disc version of Sims 3 is installed on a registry level (and I hope the origin's version isnt different), try rolling back to the date prior you updated the sims 3 from origin, the downside is that any changes and software you installed after the date will be gone but userdata will be perfectly safe(Desktop,Document, Download)
But if your game is installed on different partition than windows, system restore may not help.
or just you know, reinstalling the game from scratch.
