Auto lip sync add on not showing up in tool shelf

i have been trying to figure out how to load the auto lip sync and MHX lip sync tools to Blender 2.66. I can get the header for the tool shelf to show but that is it. Has anyone had similar issues. I have several characters I am animating and this add in would make life a lot easier. There doesn’t seem to be a lot of info out there on this add on Thanks
