Soap Skin & Bubble plug-in on mac

[Jezter]

Hi,
I've downloaded the 1.04 plug in and installed into the tools folder as described. I am running on a MacBook Pro 2.4ghz Core 2 duo. I get the toolbar and I'm able to create a skin fine and set the pressure and x/y ratio. When I try and make the soap bubble it shows copy in the top left that the script is running but it does nothing. There is no change to the skin and no text generated as I see happening on the video tutorial. I am going crazy trying to get this to work. Yes, I'm running the SketchUp pro v6 also and it's the latest update. My system is running 10.5.4.

Any ideas out there about what I can do? Any advice much appreciated.
