Moviecliploader in timeline problem

1

i’m making a preloader for my components, xml, webservices,… in one fla
So when my library is preloaded, i’m moving to frame 15 where i start a movieClipLoader.(Let’s say I load menu.swf in my index.swf )

When i test my movie, the menu.swf loads, because i see my traces from in that movie, but i don’t see the movie menu.swf!!!

I tried
var loader = new MovieClipLoader();
loader.loadClip(url, menuHolder_mc);

and

var loader = new MovieClipLoader();
loader.loadClip(url,0);

but I only saw my traces and never the movie! Strange!
Anything who had the same problem??
