Corrupted World

My problem occurred last night, as I tried loading the game. I clicked my world, and it got stuck on Building Terrain, until the game crashed. I found out that the file got corrupted somehow, so I learned how to remove the corrupted file, but Minecraft still crashes, this time saying I have 'no storage left', despite my game having only 1 world and plenty of storage remaining. Any assistances to remedy this problem would be greatly appreciated.
