Preview Adaptive skin not working

[bomjak]

I often create new topology by using the ZSphere rigging / edit topology method. (http://docs.pixologic.com/user-guide/3d-modeling/topology/zsphere-topology/) However today when I press Preview Adaptive Skin on the Adaptive Skin palette, nothing happens. The button doesn’t stay lit. I’ve been using this method for years and all of a sudden it’s stopped working.

Does anyone have any ideas what is wrong? It’s driving me crazy.
Thank you.

I’m not sure if it’s the best solution, but this seems to work:

After clicking ‘Edit topology’ I manually (alt-click) delete the initial point that the Zsphere is linked to. (The ‘Delete topology’ button doesn’t work). I then draw out the new topology. I’m not sure why all of a sudden there is an initial point that messes up any new topology…
