I must have missed the button for some reason...you sure you didn't accidently break it?
I have made a V.2 a cleaner, more compact version of the previous one : http://www.minecraft-schematics.com/schematic/6873/
It doesn't matter anyway because V.2 is way better (basically that means download it right now! :) ).
Thanks for telling me of the potential problem anyway.
