Help with a puppet?

Hello,

I've been using the Beta CA since its release.  A few weeks ago, I had my puppet working successfully, but after I had to modify some art and rearrange some layers, the rig broke.  I can't get it working again.  I've watched the videos, I've compared my puppet to your body tracking puppets and I can't for the life of me get my puppet's feet to pin to the ground.  Any advice would be greatly appreciated.
