Preloader problems - disappears at 60%

Question

Hi,
I have two Preloader problems for a project I'm working on right now.
1. The Main Site preloader disappears when 60% is loaded...with a blank screen lag until moving to the main screen
2. My external .swf Preloader is still on screen after an external .swf has loaded. I can hear the external .swf playing while watching my loader bar at about 20-40%.
I'm going to show the code I have for each...hopefully someone can help. Thanks!
Main Site Preloader:
var yChange = 109.2;
var yStart = 330.2;
myInterval = setInterval(preload,100);
function preload() {
var current = _root.getBytesLoaded();
var total = _root.getBytesTotal();
var pctLoaded = Math.round(current/total*100);
mask_mc._y = yStart - yChange/100*pctLoaded;
if (current >= total) {
  clearInterval(myInterval);
  gotoAndStop("Main",1);
External SWF Preloader:
var mcLoader:MovieClipLoader = new MovieClipLoader();
var myListener:Object = new Object();
mcLoader.addListener(myListener);
myListener.onLoadProgress = function(target_mc,bytesLoaded,bytesTotal) {
extLoader_mc._visible = true;
var pctLoaded = Math.round(bytesLoaded/bytesTotal*100);
extLoader_mc.extLoaderBar_mc._xscale = pctLoaded;
if (bytesLoaded >= bytesTotal) {
  extLoader_mc._visible = false;

change soundHandler in the fla to:
// this code below is on the main timeline?
var soundHandler:AdobeCaptivate.rdSoundHandler = new AdobeCaptivate.rdSoundHandler(this);
and change rdSoundHandler:
import AdobeCaptivate.rdSound;
import flash.display.MovieClip;  // if this is as3
class AdobeCaptivate.rdSoundHandler extends Object
var m_sounds:Object;
var m_movieSound:rdSound;
var mainMC:MovieClip;
function rdSoundHandler(mc:MovieClip)
  m_sounds = new Object();
  m_movieSound = null;
  mainMC=mc;
function attachSound(key:Number, id:String):rdSound
  var sound:rdSound;
  if(m_sounds[key] == undefined || m_sounds[key] == null)
  { //attach new sound to the handler
   var newSound:rdSound = new rdSound(mainMC);
// and now you have to find rdSound() class and post that
   newSound.attachSound(id);
   sound = m_sounds[key] = newSound;
  else
   sound = m_sounds[key];
   sound.stopSound();
  return sound;
function detachSound(key:Number)
{ //remove the sound object from the handler
  if(m_sounds[key] != undefined && m_sounds[key] != null)
   var sound:rdSound = m_sounds[key];
   sound.stopSound();
   m_sounds[key] = undefined;
function playAllSounds(bPause:Boolean)
  if(bPause == true)
  { //pause all sounds
   if(m_movieSound != null)
    m_movieSound.pause();
   for(var key in m_sounds)
    m_sounds[key].pause();
  else
  { //resume all sounds
   if(m_movieSound != null)
    m_movieSound.play();
   for(var key in m_sounds)
    m_sounds[key].play();
