I have shape bender plugin on my computer and it works perfectly on Sketchup Pro 2013.

When I open Sketchup Pro 2014 I get the following message:
Error Loading File clf_shape_bender_loader.rb
Error: #<LoadError: cannot load such file -- progressbar.rb>
/Applications/SketchUp 2014/SketchUp.app/Contents/Frameworks/Ruby.framework/Versions/2.0/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in require' /Applications/SketchUp 2014/SketchUp.app/Contents/Frameworks/Ruby.framework/Versions/2.0/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in require'
/Users/myname/Library/Application Support/SketchUp 2014/SketchUp/Plugins/clf_shape_bender_loader.rb:22:in `<top (required)>'

I am using a 2012 MAC, Software OS X 10.9.3
I am not computer savvy and do not want to mess things up. I would greatly appreciate any help or direction on who would be able to fix. Thanks.
