Preloader does not addChild on event

programming flash
1

Hello I have a website file that I am preloading with an another swf preloader file.
The code is on the first frame of preloader.swf and as follows:



import flash.display.Loader;
import flash.display.Sprite;
import flash.events.Event;

var contentLoader:Loader = new Loader(); 
 

contentLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, loading, false, 0, true); 
contentLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, contentLoaded, false, 0, true); 

contentLoader.load(new URLRequest("content.swf")); 
	
  
function contentLoaded(evt:Event):void {
	//Optionally change to a clip holder and set progressbar visibility.
	
	removeChildAt(0);
	
	addChild(contentLoader.content); 
	
	contentLoader.contentLoaderInfo.removeEventListener(ProgressEvent.PROGRESS, loading);
	contentLoader.contentLoaderInfo.removeEventListener(Event.COMPLETE, contentLoaded);
	contentLoader = null;
} 
  
function loading(evt:ProgressEvent):void { 
	var loaded:Number = evt.bytesLoaded / evt.bytesTotal; 
	setBarProgress(loaded); 
} 

function setBarProgress(value:Number) { 
	trace('Progress'+ value);
	loadtext.text = "Loading %"+ Math.floor(value * 100);
}

The problem is when I use this without simulate download option I see it is loaded via trace() and content.swf loads BUT when I use simulate download or upload files to Web and try it there it just counts to 100% percent and stops there.

Any ideas ?

Thanks
