Please help with this script, AS3 to AS2(preloader)

Question

Hi. Ive made a flash banner for my client. It have two scenes, preloader (with percentage and animation (in 100 frame)) and the main scene. Preloader uses AS3. I need this convert to AS2. How to do this? The code:
import flash.events.ProgressEvent;
function update(e:ProgressEvent):void
var percent:Number = Math.floor( (e.bytesLoaded*100)/e.bytesTotal );
if(preloaderMC is MovieClip){
preloaderMC.gotoAndStop(percent);
preload_txt.text = String(percent) + "%";
if(percent == 100){
play();
loaderInfo.addEventListener(ProgressEvent.PROGRESS, update);
// Extra test for IE
var percent:Number = Math.floor( (this.loaderInfo.bytesLoaded*100)/this.loaderInfo.bytesTotal );
if(percent == 100){
nextFrame();
stop();
The full FLA: http://www.agroinvent.eu/briklis.fla, if someone can repair(make) it, pls send me the corrected fla file.
BIG THANKS. BEST REGARDS. Zolee

use:
var tl:MovieClip=this;
function update():Void
var percent:Number = Math.floor( (tl.getBytesLoaded()*100)/tl.getBytesTotal() );
preloaderMC.gotoAndStop(percent);
preload_txt.text = String(percent) + "%";
if(percent == 100){
clearInterval(preloadI);
tl.play();
clearInterval(preloadI);
preloadI = setInterval(update,100);
stop();
