When I start it from Window/Python Scripts I can run WW - haven't had time to do anything but the Make Art button works :)

It's just when I try to access it with the one-click solution from the Scripts menu that I get nothing at all.  Running Python Shell also gives me the same error message as stepson.

Other scripts work, for example delete lights from Utility works fine from the Scripts menu.

Oh forgot to add, if I go Scripts/WW I get nothing.   If I then open the python scripts from Window menu, WW has already initialized and I'm in that menu.  So it does initialize but I get no message or anything.
