What am I doing wrong

I have attached the fla in a zip file for this problem

open it and publish. in the text box enter the path for an mp3 on your own machine

eg. c:\myTune.mp3

click on the circle - the tune plays in IE - but I can not get it to work in Netscape 7.

I have also tried it with a url to my live server

http://www.it-training-development.com/will.mp3

this works on both - not my tune - smallest one I could find…

any ideas…

I have Shockwave Flash 7.0 r19 plugin in Netscape
