Soap Skin & Bubble Extension

Hi There, Recently viewed a Tutorial with Aaron modelling a bag of Chips. Brillaint video as usual! Problem I am having is with the Soap Skin & Bubble Extension - once I generate soap skin & set my grid on a simple square; I click on the Face and the Grid disappears? Cannot seem to get past this first stage; can anyone help? Thanks, Jerry.

Hit Enter, not click on face!

Soap skin and bubble works on a closed loop of lines, not faces.

RELEASE A DOZEN WHITE DOVES! Something soooo simple that i missed! Thank you!
