texturepacks no longer work

I have a texturepack called round sun and moon pack. some of you might have heard of it. it worked fine since minecraft 1.0
now that I downloaded the new snapshot it no longer worked and I went to the texturepacks in main menu, it said "incompatible" in red.
I knew that was because of the new texturepack system. so I downloaded a the unstitcher tool dinnerbone created. I launched it and chose to convert this texturepack. after it said it was done I started minecraft and went to the texturepack folder. it now said"incompatible-converted round sun and moon pack".

what I expected to happen was: the texturepack got converted and would work.
what actually happened was : the texturepack still didn't work.

steps to reproduce
1. download texturepack
2. download unstitcher
3. place converted round sun and moon texturepack in the .minecraft texturepack folder.
