Best place for errors?

[Bob90]

Hello SketchUcation,

I have this error msg in ruby console when I right-click on a joint and try enter joint properties.

@unknownuser said:

Error: #<NoMethodError: undefined method setJointSettings' for MSketchyPhysics3:Module> C:/Program Files/Google/Google SketchUp 7/Plugins/SketchyPhysics3/JointTool.rb:650 C:/Program Files/Google/Google SketchUp 7/Plugins/SketchyPhysics3/JointTool.rb:650:in call'

Does anyone have an idea why this might be?
I'm using version 3beta and have previously installed 2, but have removed it.

Thanks,

Rob
