Soap Skin & Bubble

I having trouble using this extension. I’m trying to put a face on a curved surface using soap skin, and I’ve been unable to get it to complete the skin. I also can’t get the skin to bubble once its done. Could someone look at the video and help me out?

Attached is the file with the skin.

I would suggest to use Curviloft in this case instead…
