Saved data not loading :c

So my game had some trouble loading in when i would insert it, but it wasnt only this game so i restarted my xbox because i got a new disc and still wouldnt load. When i restarted my xbox, the game started working but all my data wouldnt load. I let it sync all night long and it finished in 3 hours but none of my saved data had loaded. I dont want to have to restart from level 1 again. Can someone help me figure out how i can get all my data back? :frowning:
