AS2 loadClip button functions stopped working

programming flash
1

created a .swf that continously scrolls with a pause and play button with only actionscript. The file was too large so I created a preloader in a seperate file loading the .swf with loadClip, but the buttons on the .swf stopped working! What do I need to do to get the buttons working again? I’m completely baffled.

You can see what I mean by looking at the two .swf’s:
www.firstchoicelandscaper.com/slideshow.swf
www.firstchoicelandscaper.com/slideshowpreload.swf

Here’s the code I use for the preloader and the loadclip:
var mcl:MovieClipLoader = new MovieClipLoader();

var mclL:Object = new Object();

mclL.onLoadProgress = function(target,loaded,total) {
loader.percent.text = Math.round((loaded/total) * 100) + “%”;
}

mclL.onLoadInit = function() {
loader._visible = false;
loader.percent.text = “”;
}

mcl.addListener(mclL);

mcl.loadClip(“slideshow.swf”,holder);

var mcl:MovieClipLoader = new MovieClipLoader();

var mclL:Object = new Object();

mclL.onLoadProgress = function(target,loaded,total) {
   loader.percent.text = Math.round((loaded/total) * 100) + "%";
}

mclL.onLoadInit = function() {
   loader._visible = false;
   loader.percent.text = "";
}

mcl.addListener(mclL);

mcl.loadClip("slideshow.swf",holder);
