Help with error code?

Okay, so this has been happening for quite a bit. At first, I thought it might have been related to some plugins I recently installed although after disabling them, it still happens. I updated Bukkit from 1.4.6 (which was also happening) to 1.4.7 today and it's still occurring.

Code:

Make sure your plugins are updated, i recommend you use the craft bukkit up to date plugin find it at
http://dev.bukkit.org/server-mods/craftbukkituptodate/
It doesn't auto update your plugins it downloads new versions in the bukkit_update folder so you will have to manually update them.

 

I already have a plugin that checks if there are any updates to my plugins and all my plugins are up to date. I don't have any old plugins that are inactive anymore either.

 

that error is a chunk corruption error.

 

So would I have to use like chunkster to fix it?

-edit-
Since chunkster is outdated, I tried using Minecraft region fixer which I can't seem to get working. I read somewhere that you can use MCedit to fix it but it won't work either. Any suggestions?
