Sims 4 update has deleted everything!

Hello, on the 2nd June I clicked to load up Sims 4; Origin had an update to do (I presumed this was a normal update since it highlighted it was updating bug fixes etc) however, once it was completed and my game finally booted EVERYTHING was gone! I have no saves! There are none to be found in my saves folder in my documents either! 

The game wanted me to start from the beginning, creating a character, just like when the game was first installed!

I still have the holiday celebration pack but not the clothes etc given at Valentines. 

My Origin account still says that I have 245 hours of playing time, yet there is no evidence of this any more ☹️

I've tried restoring my PC to a previous date, but that has made no difference, they're still all gone. 

Please if someone has had this issue can you help! 

Thanks!
