Actually, there are two problems. They are program problems, I think, not my.
Please look it, maybe you´ll help to find some solution.

First:
Look http://www.rafanda.cz/flash/index.swf link. This is my last project, a
web in flash. The problem is in preloader. Script of preloader is fine. I was
testing it by Control>Test Movie and there View>Simulate Download, and as
normal local opened swf file. Everything is fine, BUT - I exported html from
Flash, edit it (edited script is correct), and open. The preloader didn´t work!
The first (preloading movie) worked correcly, but in the second (preloading mp3
file), didn´t work function getBytesTotal(). It´s the same when it is uploaded
on FTP. Why?

Second:
Look at http://www.rafanda.cz/flash/. As you see in a code, it´s edited html
exported from Flash8, with Active Content Update. There´s an error saying I
didn´t run command Apply Active Content Update, but I run it !! I didn´t get
this error, when I tested it locally on my computer.

Please try to help me with it, I really don´t know how it can be solved. I
think I tryed everything. Thank you.
