Vertex Animation Script for Blender 3D Users

Forgive me but I’m very new to Blender but saw that this want something that would work great for me. The problem I keep getting is that the offset is a solid black bar most of the time. I’m not sure what I’m doing wrong but I do have a mesh that transforms into another shape over the course of several keyframes.
Several questions i have would be:
Do I use shape keys to make the different shapes of the mesh?

Do I use have to set keyframes for the time?

If I use shape keys do I select just the one object I have all the shape keys on when I hit the Process Anim Meshes?

If I don’t have to use Shape keys can I just have copied the mesh several times and changed each one for the different frames?

After all that I found that after running through this and the doc that’s listed I get a un-moving material. Any help would be appreciated.
