I am using Visual Studio 2013 Professional Update 3 and I have installed the latest version of Web Essentials (updated 8/8/2014), but I receive this error about 90% of the time I build or save. I even check out the source js/html files and all the existing files in the bundles folder from TFS before building. Any ideas on what else I can do?
Error generating the bundle. See output window for details
