Yes I do,....but I have the Podium V2 beta, do you think this program may produce the error?, it will be better to uninstall the Podium V2?
Many thanks for your quick answer!

I'm a SketchUp 2013 user I've already installed the RoundCorner plugin and since then when I start using the SketchUp this message appears ....Error Loading File Utilities/utilitiesTools.rb
Could not find included file 'Utilities/utilitiesTools.rb'

Anybody knows the solutions to avoid this annoying start window?
