Swf CMS embedding problem

[Token]

Hello!
(I'm not sure if this section is right for this thread, so if not, please move it.)

I've created swf using Flash 8. So when I opened it in Flash Player 7 it didn't work correctly. It's alright. Then I uploaded swf to a server and opened it in a browser with flash player 9 plug-in - so it worked correctly.
But then I inserted swf on a site's page using CMS - Joomla - and now it doesn't work correctly - it works in a way like I have Flash Player 7 plug-in installed.

I just can't understand what is the problem, and need help!
Thanks in advance!

It looks like I found the reason of the probem. I suppose it's in security setting or something like this.

My project consists of many swf files: one loads another.
index.swf is situated in root of a site, and others in the folder swfs.

So is there any security settings I should set in this situation, because I exported all fla files with default settings?
