Sims keep crashing after last update

The same thing happened to me after the update and it worked when I tried a new save file as well. But, I make copies of my "saves" and "tray" folders every other day so I tried my copy save folder I made on the 27th and it also worked, although I didn't use it. I'm not sure if you tried it but what I did is go into the "saves" folder of the save that kept crashing and first removed the file ending in ".save."

 I then picked the most recent ".save.ver(insert number) backup file which is ".save.ver0" (but you can choose any of them) and removed the ".ver0" part of the file name and it then converted into a save file type.  Doing that loaded it back to the second most recent save state and it worked fine for me but you may or not have to try with the other versions if that one doesn't work.
