Load Movie in AS3 for cd-rom output

Question

I have a .project with multiple >SWF's, which links to many other flash movies...I want to open each of the movies
in it's own window, but not in a browser. (CD-rom output). The complete project is like a book with PREVIUS and NEXT buttons. Each one unloads the current  SWF and opens a new one.  .
I have used the following script in AS2 with great success. However I haven't found the way to achieve the same result in AS3. Here is my AS2 script.
on (release) {
loadMovie("CD09.swf", _root);
I know that this is very basic but I can not write a script to achieve the AS2 Result.
Your help is very appreciated.

I appreciate your input. Wrote the code as follows: (remove the "private" because the code is in the timelinI appreciate your input. Wrote the code as follows: (remove the "private" because the code is in the timeline)
//back_btn button function
back_btn. addEvent Listener(MouseEvent.CLICK,mouseClick);
function mouseClick(event:MouseEvent):void {
var _content:DisplayObject;
function loadContent(content:String):void {
     if(_content != null){
        removeChild(_content);
        _content = null;
      var loader:Loader = new Loader();
      loader.load(new URLRequest(content));
      _content = addChild(loader);
     loadContent("CD09.swf");
The parent file loads but when pressing the back_bth. button to load the new file NOTHING HAPPENS.
I have been trying to solve this issue for a long time and I am sure we are almost there. Your kindness is very appreciated!
