Preloader issues

Hi
I have an issue that maybe doesn’t concern only me.
The issue is how to make an effective preloader when I have an accordion component on stage ( as navigation on frame 2). When using the accordion I have to export the file in AS2 maybe this is the problem why this preloader doesn`t work(view the fla. of the preloader) when is placed on frame 1
Can you refer to any usefull link or fla. would help a lot.

thanks
