Broken Game

When the first update came out for the sims for the ‘Forever Friends’ my game kept on crashing every time I loaded it up, it finally fixed itself after a few days and deleted all of my saves including my not so berry that I have been doing for 2yrs. Now I’ve just done the update for the new Adventure Awaits pack and it’s done it again. All I want to do is play my game and I can’t :((
