game keeps crashing

I was in bed and some one else could not sleep because of monsters. when I tried to get out of bed to help kill the monsters the game crashed. It will no longer load the world. When I go into the world it says leave bed and when I do the game crashes. I have attached the file of the game. I have completely shut down my computer, and that does nothing. we tried to copy the file to open it on another computer and it still crashes.
