TextureEnder just ReZips my pack

So, my problem is this: I am currently making a texure pack called Nocturnalis Reloaded. I'm currently attempting to update from MC version 1.5.2 to 1.6.2. So I downloaded the TextureEnder.jar and tried to convert the pack, but when the screen came up while it converted, it gave me maybe 20 lines, which you can see by viewing Capture.png.

I dont reallly know how you could go about reproducing this, as it seems to happen randomly. I can tell this because about a month ago when the snapshot came out introducing Resources packs, the textureender worked perfectly, but now it basically just rezips the pack.
