I'm just getting my CNC up and running, and I'd like to use this plugin, but I can't seem to get it to load in the new version, Sketchup 2015. I have unloaded it into the correct folder (per Sketchup's own instructions, but it still doesn't want to load).

Did try renaming the files from *.rb to *.rbz, but got an error when I tried to open the extension automatically using the Sketchup plugin installer.

Thoughts?
