Preloader stops and does not load content

preload stops after 2nd visit to site

[Walley]

When I first visit the site for the first time the preloader works perfect and plays the movie.

After I close my browser and go back to the site, the preloader just stops at 0% and does not play.

stop();
//Preloader
loaderInfo.addEventListener(ProgressEvent.PROGRESS, updatePreloader);
function updatePreloader(evtObj:ProgressEvent):void {
//Container for the progress of the site (download)
var percent:Number = Math.floor((evtObj.bytesLoaded*100)/evtObj.bytesTotal);
preloader.text = percent+"%";
if (percent==100) {
play();
}
}

I'm thinking I have to do something like this:

if (bytesLoaded == bytesTotal) {
play();
}

or

if (percent==100) {
play();
}
else {
play();
}

That just gives me errors. This is my first time attempting AS3.

Maybe a caching issue?

If I go to the page it loads fine. If I click on the address bar with the url already in it; it stops in the first frame which is the preloader. If I close out the tab and retype the website name it runs like normal.
