问题
Okay, so When I run my loader.swf, it's loads my game.swf perfectly fine. But when I stimulate download, at exactly 70%, My music of game.swf starts playing and it shows following errors:
TypeError: Error #1009: Cannot access a property or method of a null object reference. at GAME_fla::MainTimeline/frame11()
And
Error #2044: Unhandled IOErrorEvent:. text=Error #2036: Load Never Completed.
The game works perfectly fine when loaded normally. This issue persists when I upload it online and check if it's working. It doesn't. My loader works well for other swf files. How to solve this?

}If I add them, other frames are not being able to access those variables.
Loader code before:
var myrequest: URLRequest = new URLRequest("GAME.swf");
var myloader: Loader = new Loader();
myloader.load(myrequest);
myloader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, progresshandler);
function progresshandler(myevent: ProgressEvent): void {
var myprogress: Number = myevent.target.bytesLoaded / myevent.target.bytesTotal;
bar_mc.scaleX = myprogress;
percentage_text.text = Math.round(myprogress * 100) + "%";
}
myloader.contentLoaderInfo.addEventListener(Event.COMPLETE, finished);
function finished(myevent: Event): void {
addChild(myloader);
removeChild(percentage_text);
removeChild(bar_mc);
removeChild(background_mc);
}Loader Code After:
var myrequest: URLRequest = new URLRequest("GAME.swf");
import flash.net.URLRequest;
import flash.display.MovieClip;
import flash.events.Event;
var myloader: Loader = new Loader();
myloader.load(myrequest);
function progresshandler(myevent: ProgressEvent): void {

}
function completes(myevent: Event): void {
var loaderInfo: LoaderInfo = myevent.target as LoaderInfo;
var swf: Object = loaderInfo.content;
swf.play();

Maybe you should give a try to this event: ADDED_TO_STAGE. The ADDED_TO_STAGE event is triggered when an object is added to stage (very curious name and correlation), that is when you execute an addChild method.
Try to listen to this event in your Main class of your external SWF, so, no code will be executed before you add this respective object to stage (now you can hear the music even during the load process.
Follow some example:
package
{
import flash.display.Sprite;
import flash.events.Event;
public class TheMainClassOfYourExternalSWF extends Sprite
{
public function TheMainClassOfYourExternalSWF()
{
addEventListener(Event.ADDED_TO_STAGE, initHandler);
}
private function initHandler(event:Event):void
{
removeEventListener(Event.ADDED_TO_STAGE, initHandler);
trace('this is the stage:', stage);
trace('this is my parent:', this.parent);
// here you start to include your logic
}
}
}
if you are using a FLA file and adding your code using timeline, you can try:
addEventListener(Event.ADDED_TO_STAGE, initHandler);
function initHandler(event:Event):void
{
removeEventListener(Event.ADDED_TO_STAGE, initHandler);
// here you start to include your logic, call your functions, initialise your instances...
}

When loading an external swf there are 2 things to be aware of.
First the first frame of the loaded swf start playing when the Event.INIT triggers not when the Event.COMPLETE triggers. The event init triggers when the first frame can be played while the complete triggers when the whole swf is loaded.
Second stage or root is only available in the loaded swf when it had be added to a display list that is added to the stage. A loaded swf has no stage or root when the Event.INIT triggers so the first frame of the swf should not have any reference to stage or root.
If you do not use a document class with your swf then make your first frame empty with just a stop() then once loaded and added to a display list make your swf go to frame 2 where you have all your code.
