When I tried to load my immortal dynasty today, it came up with an error that read something like: "A serious error has occurred while try to load "SheoDynasty15.sims3", it is recommended to restart the game". Eventually it just quit, so I tried to load it again and the same thing happened. Is there some way to fix it or is that save lost? And if I can't get it to work, would I be able to go back to my previous save?
