I installed VWD on Daz Studio a while ago and have used it multiple times with success.  Today I can't get it to function, and I'm wondering whether I had a stroke and forgot something vital. dordle

I set up a scene using a cube and a plane.  The plane is higher than the cube, and the time line is 30 frames long.

I launch VWD, choose the cube, and then push collision twice.  Next to the cube, the list now says collision. I select the plane, then cloth, and then cloth again.  It is now classified as cloth.
