I cannot activate the Sandbox tools by following the instructions in the manual. Under Preferences>Extensions, I am offered only the two choices: Ruby Script Examples, and Utilities Tools.

In the Google Sketchup 6>Sketchup>Tools, there is a Sandbox folder, containing such tools as Smove Tool.rbs, so I'm pretty sure the problem is one of access only.

When I quit the program and then restart it, this error message is displayed: "Error loading file Sandbox Tools.rb wrong number of arguments (2 for1)."

I have tried reinstalling the program over the existing one with no success. I am reluctant to wipe out the existing program and reinstalling I want to retain existing templates, components, and the like.

Any suggestions?
