How to stop looping an external .SWF file?

Hi,

How can I stop my Logo.swf file from looping. Actually the external Logo.swf file doesn’t contain any looping code inside it. If I open it in any flash player it animates only one time.

Writing “stop();” in code stops all other animations which I don’t want.

 
var J:Loader=new Loader();
addChild(J);
J.load(new URLRequest("Logo.swf"));
J.x = 275;
J.y = 25;
J.contentLoaderInfo.addEventListener(Event.INIT, growLoaderj);
 function growLoaderj(evt:Event):void {
     J.width = 1000;
     J.height = 700;
}
var myTimer:Timer = new Timer(2000,3);
myTimer.addEventListener(TimerEvent.TIMER, timerListener);
function timerListener (e:TimerEvent):void{
trace("Timer is Triggered");
J.alpha=0;
}
myTimer.start();


Any help please.
