Photo Gallery Using XML and Flash

Hey there!
Im new so bare with me.
I couldn’t download the following tutorial FLA’s for the following tutorial:
http://www.kirupa.com/developer/mx2004/xml_flash_photogallery.htm

But i have been able to use the code and the tutorial to create a gallery.
The gallery works…well almost…
I cant get the preloader bar to work, i guess the movie clip has some actions which i don’t know.
Although the keyboard arrow keys can control the pictures, the previous and next buttons work, only if you press them twice and this skips pictures…
Just wondering if you guys can help by downloading the fla and telling me the actions that the keys / preloader have.
Thanks in advance,
Stickeh
