Sims 3 Late Night now working?

I have the Sims 3, Late Night, Ambitions, World Adventures all downloaded from various torrents. I've had Sims 3 LN installed on my laptop for at least a month or two, and it worked flawlessly. Last week I tried to update all the EPs and the base game to the latest version, but it didn't work, so I restored the back up files (from when it WAS working) and whenever I open it up it gives me the disc authentication error. Is there a way to fix this?
