SIMS4 PC Playing history GONE!

I logged in to find the last two years worth of playing has vanished! I get to the main menu, and it only lets me play "scenario" or create a sim. I spoke to the chat  team and did EVERY trouble - shooting step. ( i did every step over 3 times! - My pc has not changed. I deleted the app, reinstalled , repaired.. Did their " file change suggestion" and still all my history from the last 2 years is gone! - Nothing has changed, no firewalls etc. I can see all my add on packs etc.  However, it will not load or show any previous game play. The rental houses are not there. The household is not there to play. It has all just vanished...... Has anyone had this happen to them????
