Your SCF user-profile SketchUp version is not matched by your error-message's version ... You probably have an old version of that 'helper' rb installed in v2014.... In v2014 'togglewindows' is really not needed. Although it's included as a helper in some plugins, the latest version should spot it is not compatible with v2014 and therefore abort its loading, and so not cause these errors... I suspect you have ill-advisedly just copied some Plugins files over from an earlier version of SketchUp. This is NOT recommended ! Get/install new versions wherever possible...
