My game save won't load

I wanted to play on my copy of Forza 4 because i wanted to race my stock car, but when I played the game, it restarted me! I haven’t been on it for a year and i know it wasn’t because of a ban. Can someone help me. I already contacted 2 companies on this.

Are you still playing on the same console? If you are, have you possibly deleted your Forza 4 game save? If you have changed console & never kept your original game save then it’s lost & you’ll have start over again, same applies if you have somehow manged to delete your game save.
