ME Legendary Edition, Save files get deleted after the game is closed.

Hi,

I've purchased ME Legendary Edition today, played it all day, and after I closed the game and restarted it my career was gone. I had about 10 hours of gametime already on my character, now I can't load any save. There are no save files in the game folder. I've tried creating a different character, saved the game, closed the program, and after restarting it the character was gone again.

Any help with this?
