Sims 3 Pets Cannot (load/start new) games. [CLOSED]

I downloaded your fix pack, and i still get this problem where my computer says sims 3 has stopped working, after i try to start a new game or load my old one.

I also get this message before the game goes to the loading sequence.
"It looks like you have installed an unofficial game modification that does not match your current version of the sims 3. We recommend that you either uninstall these game modifications or get updated versions of them - otherwise you may experiences crashes or significant bugs."

Please help

Thanks for your time.
