mys sims world will not load

Hi, 

My Sims 3 world will not load at all it comes up with a error saying "A serious error has occurred while loading 'Sunset Valley.World'. It is strongly recommended that you restart the application" 

I have restarted my Computer and also uninstalled the Sims & origin but the error is still popping up. 

i have the supernatural and ambitions  expansion packs there worlds are coming up with the same error as well. 

HELP!
