Preloader screen not showing on browser

[flash_newguy]

Hi. I designed a website for a company recently, and had a preloader screen for it. Now that its uploaded, when I visit the website, the browser downloads all the data first before displaying it, alright. But the preloader screen doesnt appear. What could be the problem?
When I simulate download in the swf, it shows the preloader screen properly. Any suggestions?

The AS on the 1st frame is something like this:

bytes_loaded = Math.round(this.getBytesLoaded());
bytes_total = Math.round(this.getBytesTotal());
getPercent = bytes_loaded/bytes_total;
this.loadBar._width = getPercent*100;
this.loadText = Math.round(getPercent*100)+"%";
if (bytes_loaded == bytes_total) {
this.gotoAndPlay(3);
}


and the 2nd frame simply has a GotoAndPlay(1); command
