Error #2044: Unhandled IOErrorEvent:. text=Error #2035: URL Not Found

If you see the above error don't waste much time but debug your application from start point i.e. s:Application (flex 4) or mx:Application (flex 3) and see if you have any custom preloader. If you have provided wrong url it will fail.

Otherwise make sure your images are in right path basically it is URLRequest (url--> problem)..
