Preloader problem

Hi everyone.

I have fully working preloader (tested), but I can’t start my swf file. It says:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at GameClass$iinit()

I can’t figure out what is wrong. I have these files:

  • Game.fla
  • GameClass.as (this is Document Class)
  • Varijable.as (just another as for my Game)

and of course Game.swf

Also in GameClass.as I have including external sound loop for my file.

My swf file runs normally with music and stuff.

For preloader I have:

  • Igra.fla
  • Preloader.as

When I start my preloader, I get this error, but weird thing is that I hear my sound loop but don’t see my swf.

Here is preloader code:

package 
{
    import flash.display.Loader; 
    import flash.display.LoaderInfo;
    import flash.net.URLRequest;
    import flash.events.Event;
    import flash.events.ProgressEvent;
    import flash.text.TextField;
    import flash.display.MovieClip;
    
    public class Preloader extends MovieClip
    {
        var myLoader:Loader = new Loader();
        var myRequest:URLRequest = new URLRequest("Game.swf");
        
        public function Preloader()
        {
            myLoader.load(myRequest);
            myLoader.contentLoaderInfo.addEventListener(Event.OPEN,showPreloader);
            myLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS,showProgress);
            myLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,showLoadResult);
        }
        
        function showPreloader(event:Event):void 
        {
            loadProgress_txt.visible = true;
        }
        
        function showProgress(event:ProgressEvent):void 
        {
            loadProgress_txt.text = "Loading game: " + event.bytesLoaded;
        }
        
        function showLoadResult(event:Event):void 
        {
            loadProgress_txt.visible = false;
            addChild(myLoader);
        }
    }
}

PS. I tried working with preloading in my Game.swf, tried external preloader, tried with component preloader, and nothing works.
Any idea anyone?
