Embedding Issues - SWF MP3

Okay, I am not a big Flash guy, however, my colleauge designed a SWF w/ MP3, Preloader, etc for me to plug into an existing webpage. The SWF calls the MP3, Preloader from the same folder. I uploaded this folder to the server without touching anything in it.

The SWF works in the embedded page, however the audio does not. When going to the actual SWF file through a browser, The SWF works fine.

I am mostly in FF but tested it on Opera and Safari on Mac OS X.

Any thoughts on how to troubleshoot this guy?
