Flash website - transition problem - help!

1

I’m doing a website for a band (www.theaviators.co.uk) but the menu system isn’t working properly. Basically the main animation ([url=“http://www.geocities.com/gord_82/Main.fla”]download .fla here) has a blank space into which it calls the other .swf’s. I used [url=“http://www.kirupa.com/developer/mx/preloader_transition.htm”]Claudio’s preloader and transition tutorial

Now heres the strange bit. If I publish the main.fla as a .swf and play it in the standalone player - everything works (You can test this by downloading the bios.swf here and clicking on the bios button)

However if I publish the main.fla as a .swf and display it in a html page the menu system stops working.

I have no idea why this is happening and its immensly frustrating so if anyone can help it would be great.
