"broken savefile" - WHAT THE HELL'S WRONG?! How do I recover my char?!

[Nemesis]

I was clvl 40 and hanging around dlvl 90, had all the resists except for Nether and Disenchantment, +21 speed, 18/200 CON, all dungeon spellbooks, EVERYTHING! And now the game tells me the save file is broken! I could have won this game, and sure, I could have died too, but if the game's going to end, it has to be MY fault! This was my first serious vanilla character, and this is no way for him to go away! Sorry for ranting, what I really wanted to ask was if someone could help me.

Here's the save file:

It was a v3.11 game, and I had to reload it after my computer crashed. Then the game told me the save file was broken, but that doesn't make any sense! I mean, it would make sense if my comp crashed while trying to save, but that wasn't the case.

If there's no way to recover the file, is there any character editor for Angband that can help me create a new character with identical equipment, lvl, etc?
