I hate to be so stupid but I am still having trouble with getting

Skin

or

Soap Bubbles

working on my Mac Pro Laptop OS 10.4.11
I put the .rb scripts in the sketchup 7 plugins file, and also, tried them in the tools file, (both putting the .rb scripts in and out of the file they came in, inside the folder) I also put in the progressbar.rb script.

I get error messages that say it can not read the soap bubbles stuff
and skin shows up but doesnt work except to clear.

I would appreciate any help on this matter that anyone may have

thanks everyone/anyone
