Blind as a bat dumb as a rock - loader tut anguish

Ok so I’m reading up on the one frame preloader in the tutorials http://www.kirupa.com/developer/actionscript/preloader.htm
and I’m doing everything it says step by step - or so I thought but my preloader aint preloading like it’s suppose to - I think.

It seems that when i get to section iii I’m A OK, and then I do the whole copy and paste thing, but then in section v where I add my loader MC in frame 1, things just seem to fall apart.

I test the movie before adding an mp3 to it and the LOADER M seems to run just fine. Then I add the mp3 to it and the loader dosen’t do a thing. So What gives?

here is my *.fla http://www.cybersoapbox.com/graphics/Space2001TestLoader.fla
and the swf too.

So which is it am I as blind as a bat or dumb as a rock. And when your done answering that can you tell me why it aint preloading.
