Solved Server stopped working, need help

I'm running vista 64 SP2, its x86, Hamachi 2, java version 1.7.0, java SE runtime Environment build 1.7.0-b147, java HotSpot 64-bit server VM build 21.0-b17, mixed mode. The plugins i have are AuthMe, ChatManager, CivilizedSpawn, CreeperHeal, MotherNature, Iconomy, ModifyWorld, PermissionsEx, Lockette, noEnderman, and WorldEdit. My server quit a few days ago and I haven't had time to figure out the problem. Here's the log with the problems

I think that's a chunk error. Did your server quitted without saving correctly? It means you'll have to put a backup online, or export your world to a new map using MCEdit

zip

 

It may have stopped due to an unexpected shutdown. my world is still good, im using a hamachi server right now with it in it. Do I need to delete Bukkit and start over?

 

No, it's a problem with the world map wich means if your players are in a corrupted chunk, you'll get spam errors.. and you can only fix that by using mcedit or a backup

zip

 

Ok, forgive my ignorance, but so far me and one other person are the only one's who have been on this world, and it works fine for both of us without bukkit just using the minecraft server and hamachi. If I use mcedit, how do I go about fixing it? I'm pretty new to all this.
