I have been playing my game quite long now, was about to learn how to follow elder eyes soon. So i was gathering diamonds and searching villages etc. I was riding with my horse, i fell a few blocks and the game had a serious lag. I waited for a few minutes, but the game was still frozen. I got to save it, but then when i launched it, it did not launch the game anymore.

Is there any way i can get the game working anymore? I really enjoyed all my play time and would be a big waste i did not got to finish the game after so many hours of playing.

Please tell me what files i need to attach
