404 when testing game

Hi

I want to test my game using node-webkit but it isn't show (only the process showing). I've tried using Chrome but it just showing a blank screen. I just seen the JavaScript console but all js files in the server only shows a 404 error.

EDIT: I've solved the problem, Expiro viruses are stranded in my computer. I've used AVG Win32.Expiro remover to remove all viruses in files. Finally, everything's okay.
