I have a project that was working on RC and worked with no problems. Updated to RTM and now I cannot start the application
I also created a new black cordova app and
I had the same issue using Ripple Emulator. I solved the problem by deleting the cache of cordova (VS-Tools-Options-Apache Cordova Tools-Cordova Tools-Delete cache...).
I've also changed the port from 4400 to dynamic (under Ripple emulator).
