Curviloft skinning is working now, after uninstalling and reinstalling Fredo6 Tools. The disruption of began after installing Fredo6 Tools over top the already installed Curviloft.

I'm using Curviloft on a Mac. It worked great for one day. Now skinning process bar just stops with 0%. No further effort on my part seems to correct this situation. I'm trying skinning function on a very simple wire frame. Can anyone offer suggestions?
