динамическая загрузка файлов

[Stajor]

сделал контейнер, пытаюсь загрузить в него игру, получаю вот такую ошибку

ArgumentError: Error #2180: It is illegal to move AVM1 content (AS1 or AS2) to a different part of the displayList when it has been loaded into AVM2 (AS3) content.
at flash.display:isplayObjectContainer/addChild()
at Untitled_fla::MainTimeline/onCompleteHandler()

вот код

function startLoad() {
	var mLoader:Loader = new Loader();
	var mRequest:URLRequest = new URLRequest("http://www.mysite.loc/swf/game.swf");
	mLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onCompleteHandler);
	mLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onProgressHandler);
	mLoader.load(mRequest);
}
 
function onCompleteHandler(loadEvent:Event) {	
	addChild(loadEvent.currentTarget.content);
}
 
function onProgressHandler(mProgress:ProgressEvent) {
	var percent:Number = mProgress.bytesLoaded / mProgress.bytesTotal;
	trace(percent);
}
startLoad();
