Help swf loader

Question

Hello all, I use Flash CS4 with AS3.
I have a problem with the site preloader. When I  simulate the loading it is "invisible" for a while and then show up  starting loading from ~ 24-27% or maybe ~55%
To resolve  this some people suggested me to create a loader.swf (where the preload  stay) and the site.swf: when the loader.swf have loaded the site.swf  then it show up.
Well I've tried this with the following code:
var file:Loader=new Loader();
var path:String;
load.bar.scaleX = 0;
function preLoader (event:Event):void{
    if(file.contentLoaderInfo.bytesTotal != 0)
        load.bar.scaleX = (file.contentLoaderInfo.bytesLoaded / file.contentLoaderInfo.bytesTotal);
    load.txt_perc.text=String(Math.round((file.contentLoaderInfo.bytesLoaded/file.contentLoad erInfo.bytesTotal)*100))+"%";
    trace(file.contentLoaderInfo.bytesLoaded);
function stopLoader (event:Event):void{
    trace("Downloaded");
    file.removeEventListener(Event.ENTER_FRAME, preLoader);
    load.bar.scaleX = 0;
    load.txt_perc.text="";
file.contentLoaderInfo.addEventListener(Event.COMPLETE, stopLoader);
function loadMovie():void {
    load.bar.scaleX = 0;
    var swf:URLRequest = new URLRequest(path);
    file.load(swf);
    file.addEventListener(Event.ENTER_FRAME, preLoader);
    stage.addChild(file);
function path1(e:Event):void{
    path="Example.swf";
    loadMovie();
stage.addEventListener(Event.ENTER_FRAME, path1);
But it returns this error:
Error #2044: IOErrorEvent not handled:. text=Error #2036: Loading incomplete.
Someone said me that this error is due to the impossibility to find the URL of the swf but that's wrong since the swf is finded.
If I watch the loading simulation I see that several copies of the swf are "loaded" but no one arrives to the 100%.
However I've said "loaded" because if I put a trace(file.contentLoaderInfo.bytesLoaded); I see a permanent 0.
Please help me I'm going crazy!

use:
var file:Loader=new Loader();
load.bar.scaleX = 0;
loadMovieF("example.swf");
function preLoader (event:ProgressEvent):void{
    if(event.bytesTotal != 0)
        load.bar.scaleX = (event.bytesLoaded / event.bytesTotal);
        load.txt_perc.text=String(Math.round((event.bytesLoaded/event.bytesTo tal)*100))+"% Loaded";
    trace(file.contentLoaderInfo.bytesLoaded);
function stopLoader (event:Event):void{
    trace("Downloaded");
    file.contentLoaderInfo.removeEventListener(ProgressEvent.PROGRESS, preLoader);
file.contentLoaderInfo.removeEventListener(Event.COMPLETE,stopLoader);
    load.bar.scaleX = 0;
    load.txt_perc.text="";
removeChild(load);
function loadMovieF(url:String):void {
    load.bar.scaleX = 0;
    var swf:URLRequest = new URLRequest(url);
if(!file.contentLoaderInfo.hasEventListener(ProgressEvent.PROGRESS){
    file.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, preLoader);
file.contentLoaderInfo.addEventListener(Event.COMPLETE, stopLoader);
file.load(swf);
addChild(load);
