Everythings Gone!!

I have done the most recent update.  When I got back into the game EVERYTHING was gone.  All my custom content, all my builds, all my sims, everything.  I did a repair and restarted, nothing.  I went into options to make sure my custom content was turned back on and restarted, nothing.  I was told to click on the X19 (not sure) to fix it, but I don't have that option anywhere that I can find.  Can someone please help!! Thanks in advance for any advice.
