Home_btn to reload iOS app is not working???

hello again,

I can't find the solution.

I hope someone can help me because I'm desparate.

I  have a main-SFW within several levels-SWF's.

Now I want on each level a Home_btn so I can reload the app.

Here is my code in some SWF-level:

Home_btn.addEventListener(MouseEvent.CLICK, go_home);

function go_home(event: MouseEvent) {

  var appDomain_1:ApplicationDomain = new ApplicationDomain(ApplicationDomain.currentDomain);

var context1:LoaderContext = new LoaderContext(false, appDomain_1);

var loader1:Loader = new Loader();

var file1: File = File.applicationDirectory.resolvePath("main.swf");

loader1.load(new URLRequest (file1.url), context1);

  addChild(loader1);

}

in the main.SWF the level_SWF's won"t open again.

I have included all SWF's in the MainSWF and the main SWF also.

I hope someone can help me.
