Something Weird With Previewing

Whenever I try and preview a fading text I have made (http://www.kirupa.com/developer/mx/fadingtext.htm), the preview shows only the text sitting there, doing nothing. When I’m in the workspace, and go to my first keyframe and hit enter, I can view it there and it works fine. But when I try and publish preview or ctrl + enter preview, it never works. I even published it and hosted it on my site, and it still didn’t work. I know I did it right, it’s just not working. Anyone know what’s up?
