Direwolf20 (v 1.0.12) 1.6.4 World is Corrupted

[DDboom]

My Direwolf20 1.6.4 world crashes whenever I try to load it. When I load it, it returns to the title screen and then if I try to load it again my launcher crashes. This started when my computer shut down while playing on my server. I rebooted the server, and one of the chunks was unloaded. I thought nothing of it, and then my computer crashed again. This time I was unable to access the world via server or SSP. Here is the server crash log because there is no client one. http://pastebin.com/tHVHvJ6K#

-Edit: I've figured out where my problem is, but is there a way to delete the exact coordinates instead of the whole region or chunk (My base is located in the chunk)?

My did the same thing and now my save game is gone. I was playing at it crashed, when I loaded it up and I choose single player I get a ton of errors.

Hope someone can help. I had 30+ hours in my save game.

You can use MCEdit to remove single blocks.

I tried this, but instead of deleting a block I just shifted my base onto another world. Thanks for the help!
