World Unusable after Sudden Shutdown

Hi Mojang,
My world suddenly became completely unusable earlier. I was loading it then my computer shut down for no apparent reason (Maybe a power surge?) and when I started it back up, my world was still in com.mojang as a file folder, but when I try to load it, it doesn't even show up in my world menu. I have attached my world in a zip folder so you can take a look. I set the report to private because my world contains my real name in it.
