Can someone test if this works with MoI ver 4?

I installed what I believe is the latest version of the Cloth script:

Maybe I just don't know how to use it. I have a Plane with a Sphere underneath.

When I run the script, it won't let me change the grid size. I do get the full menu with the 12 sliders. Press Done to start and the wheel has been spinning for over 10 minutes.
