My minecraft save got fubar'd.

[Prox]

First of all I do not own a legit copy of Minecraft, I have a cracked client.
My internet was not working also.
I also used inveditor on that world too.

So I was playing minecraft, building stuff on my world when suddenly the power went off for like 0.1 second
which caused my computer to turn it self off.
After that I turned my computer on, I opened the minecraft client and accidentally checked the "Force Update"
and pressed "Enter game" which caused a download to start and since my internet was not working I could not
complete the download so I turned off minecraft and launched it again. Then when I went to Singleplayer all the worlds
but the one that I was playing were there. At first I thought it somehow got deleted and I went to the minecraft saves
folder to check. My world were there. Then I tried to use inveditor and I got this error:

I have no idea what's wrong so some help would be appreciated.

use WorldEdit and use the CheckForErrors(it should fix it), then save

This.

Also this is close to the error i got on my old server map.
Something about "GZip format" i don't remember what

also delete level.dat(I think it's level.dat?)

Should be a small file, in the Kb zone - at the root of the map folder
