Windows .exe World Edit with FTBBETAA

[Ashzification]

OS: Win 7 x64
Java: Java 7, u9
Launcher: 1.0.1 (tried updating, it broke, so I'm sticking with 1.0.1 until I can get 1.0.3 to work on my other computer)

I tried to update to 1.0.3, it did not work. So I opened my saved world in 1.0.1. Game crashed, no big deal. I was able to get a new world started. Not too worried at this point. Now, a couple hours later, very bored, I log in to play my saved world (I kind of really like it). And I saw this

Where there was once wasteland and a village is now randomly missing groups of blocks. (There are a few more at the end of this album: http://imgur.com/a/rlF3K#0)

So I tried to use world edit (this version: http://www.minecraftmine.org/worldedit-cui-mod/)
And when I went to open the world this error report comes up: http://pastebin.com/7duSzmLK

I don't know if I just put World Edit in the wrong place (file path: C:\Users\Ashley\Desktop\FTB\FTBBETAA\minecraft\mods) or if it won't work.

Any guidance is appreciated

Well that's interesting...... It seem to have removed every single modblock yet left every vanilla block untouched.
As if the chunks were reset and the mods weren't invited to join. Have you found any mod spawned blocks in the affected areas at all?
As for world edit, i've gotten the impression that FTB conflicts with world edit mods. You might be able to force a chunk reset somehow though.

I was just hoping to not have to replace all of the cracked sand individually. Now that my 1.0.4 download works I just started a new game with the same seed. Ans yes, all of the viewable blocks on the top layer are still cracked sand. That's what prompted my confusion in the first place. It's like the game wanted to remove the chunks, but only the modded ones, and quit half way through.
