Loader, Unload SWF and Warning: Ignoring 'secure' attribute........

Question

Hey all
I was just simply trying to load one swf into another.  in my document class I have the following line of code in my constructor.
var loadBoard:LoadBoard = new LoadBoard("Directory.swf");
in my LoadBoard class:
package com.myproject
     import flash.display.Loader;
     import flash.display.MovieClip;
     import flash.net.URLRequest;
     public class LoadBoard extends MovieClip
          public function LoadBoard(nameOfBoard:String)
               var boardLoader:Loader = new Loader();
               addChild(boardLoader);
               boardLoader.load(new URLRequest(nameOfBoard));
               trace("swf should be loaded");
In my console I get the following when I debug"
[SWF] U:\fullPath\Directory.swf - 69,058 bytes after decompression
[SWF] U:\fullPath\Directory.swf - 2,067 bytes after decompression
[SWF] U:\fullPath\Directory.swf - 322,606 bytes after decompression
[SWF] U:\fullPath\Directory.swf - 112,558 bytes after decompression
[Unload SWF] U:\fullPath\Directory.swf
Warning: Ignoring 'secure' attribute in policy file from http://fpdownload.adobe.com/pub/swz/crossdomain.xml.  The 'secure' attribute is only permitted in HTTPS and socket policy files.  See http://www.adobe.com/go/strict_policy_files for details.
Not sure why I am getting this warning, when I googled it, the erro has to do with trying to load a file from another domain. My Directory.swf file is in the same location as my main swf, the bin-debug folder.  Also the Directory.swf does not seem to load into my main swf as I don't see it show up in the flash player when i run my app.   I am also a little confused on the [Unload SWF], I am not doing anything to tell it to Unload my swf.
I am using FB to do all my coding and debugging if that matters.
Does anyone have any ideas.
thanks,

Apparently I was, so I changed it to classic text in my Directory.fla and that seemed to remove the weird error.  However it seem that my swf is still not loading.  any Ideas why that might be?
[EDIT]  Ok, my Directory swf is defenatly loading. but not showing up in the display list. I updated my LoadBoard to the following.
package com.aces
     import flash.display.Loader;
     import flash.display.MovieClip;
     import flash.events.Event;
     import flash.net.URLRequest;
     public class LoadBoard extends MovieClip
          public function LoadBoard(nameOfBoard:String)
               var boardLoader:Loader = new Loader();
               boardLoader.load(new URLRequest(nameOfBoard));
               boardLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, finishLoading);
          public function finishLoading(loadEvent:Event):void
               addChild(loadEvent.currentTarget.content);
               trace("swf should be loaded");
any Ideas?
Thanks,
