Load swf on loaded swf? - actionscript-3

Question

I'm on a project created in Flash Builder 4.7 and Flash Professional CS6, nice.
I need the project load's a SWF inside the "preloaded SWF",
The first SWF, loads a second SWF,
This second SWF would be the "Home" of the project.
At this point, it work's perfectly. But when the "Home" try to load other external SWF, it says :
[IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2124"]
The code of the first SWF:
public class InitialSWF extends MovieClip
{
private var _loader_:Loader;
private var _applicationContent_:DisplayObject;
private var _loaderContent_:MovieClip;
private var _loaderIcon_:MovieClip;
public function InitialSWF()
{
super();
_loader_ = new Loader();
_loader_.contentLoaderInfo.addEventListener(Event.COMPLETE,_onComplete_,false,0,true);
_loader_.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR,_onIoError_,false,0,true);
_loader_.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS,_onProgress_,false,0,true);
_loader_.load(new URLRequest("Home.swf"));
}
private function _onComplete_(param1:Event) : void
{
_applicationContent_ = _loader_.content;
_applicationContent_.visible = true;
stage.addChild(_applicationContent_);
_applicationContent_.addEventListener("onApplicationComplete",_onApplicationComplete_,false,0,true);
_loader_.contentLoaderInfo.removeEventListener(Event.COMPLETE,_onComplete_);
_loader_.contentLoaderInfo.removeEventListener(IOErrorEvent.IO_ERROR,_onIoError_);
_loader_.contentLoaderInfo.removeEventListener(ProgressEvent.PROGRESS,_onProgress_);
_loader_.unload();
_loader_ = null;
}
private function _onApplicationComplete_(tmpEvt:Event) : void
{
_applicationContent_.removeEventListener("onApplicationComplete",_onApplicationComplete_);
_loaderContent_.addEventListener("loaderOut",_onLoaderOut_,false,0,true);
// do something
}
private function _onLoaderOut_(param1:Event) : void
{
_loaderContent_.removeEventListener("loaderOut",_onLoaderOut_);
_applicationContent_.visible = true;
stage.removeChild(this);
}
private function _onIoError_(tmpError:IOErrorEvent) : void
{
trace(tmpError);
}
private function _onProgress_(param1:ProgressEvent) : void
{
var _progress_:Number = Math.round(param1.bytesLoaded / param1.bytesTotal * 100);
//Do animation loading
}
And the HomeSWF:
public class SecondarySWF extends Sprite
{
private var _loader_:Loader;
private var _loaderContent_:MovieClip;
private var _loaderIcon_:MovieClip;
private var _applicationContent_:DisplayObject;
public function SecondarySWF()
{
this.addEventListener(Event.ADDED_TO_STAGE,this._GoLogin_,false,0,true);
}
public function _GoLogin_(tmpEvent:Event)
{
_loader_ = new Loader();
_loader_.contentLoaderInfo.addEventListener(Event.COMPLETE,_onComplete_,false,0,true);
_loader_.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR,_onIoError_,false,0,true);
_loader_.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS,_onProgress_,false,0,true);
_loader_.contentLoaderInfo.addEventListener(HTTPStatusEvent.HTTP_STATUS, httpStatusHandler);
_loader_.load(new URLRequest("SecondarySWF.swf"));
}
private function httpStatusHandler(event:HTTPStatusEvent):void {
trace(event);
}
private function _onComplete_(param1:Event) : *
{
_applicationContent_ = _loader_.content;
_applicationContent_.visible = true;
stage.addChild(_applicationContent_);
_applicationContent_.addEventListener("onApplicationComplete",_onApplicationComplete_,false,0,true);
_loader_.contentLoaderInfo.removeEventListener(Event.COMPLETE,_onComplete_);
_loader_.contentLoaderInfo.removeEventListener(IOErrorEvent.IO_ERROR,_onIoError_);
_loader_.contentLoaderInfo.removeEventListener(ProgressEvent.PROGRESS,_onProgress_);
_loader_.unload();
_loader_ = null;
this.removeEventListener(Event.ADDED_TO_STAGE,this._GoLogin_);
}
private function _onApplicationComplete_(param1:Event) : void
{
_applicationContent_.removeEventListener("onApplicationComplete",_onApplicationComplete_);
_loaderContent_.addEventListener("loaderOut",_onLoaderOut_,false,0,true);
// ..
}
private function _onLoaderOut_(param1:Event) : void
{
_loaderContent_.removeEventListener("loaderOut",_onLoaderOut_);
//_applicationContent_.visible = true;
//stage.removeChild(this);
}
private function _onIoError_(tmpError:IOErrorEvent) : void
{
trace(tmpError);
}
private function _onProgress_(param1:ProgressEvent) : void
{
var _progress_:Number = Math.round(param1.bytesLoaded / param1.bytesTotal * 100);
// ..
}
}
ConsoleChromeSWF <-This is an image of the Google console.log, and catch this:
