EA SUPPORT

Hello. I have a problem with my The Sims 4 game. When I started a game there was an orange window with "Your saved game is in the new version of game. Please update it". There wasn't update, but when it appeared I updated my game. I lost my saved game and now every time when I play I see this orange window again. So I can't play this game every time starting from beginning. And the game loads so slowely now. What can I do with this mistakes?
