Wrong verts means you used a figure that does not have the same poly count. did you change figures? Did you load the high rez James instead of the other?

If nothing happens, it may be fine. Did you select the head and look in the dials to see if there is the morph dial there and did you dial that to 1.000.

To make sure the morph is working, you could do export steps and then delete the figure from the scene and load a the same figure back in and load the morph to it. Then there should not be a wrong vert error and the new morph should work when dialed.

Geeps tutorials have images with them and might be easier to understand than my just telling. I myself understand things better when I see it/ tear it apart and put back together than just reading.
