HELP NEEDED WITH POWERPOINT 2004 FOR MAC

Hi,
I am having a problem with my PP show. I have set up all my custom
animations, timings, slide transitions eyc, and when played the show
is fine, it does what it is supposed to do.

The problem comes when I add an Mp3 music track to slide one. I set
it to play automatically as opposed to clicking to start. I also set
it in custom animations to the first item in the list on slide one in
order that when the show starts the music comes in straight away.

This appears to be where the problem starts. The music plays, the
first piece of text animates and then nothing else happens, the rest
of the animations freeze, despite being selected to start 'after
previous' in the animation list.

If I delete the music icon, the small speaker symbol, then the show
plays fine again.

Any ideas what's going wrong here, and instructions on how to add
music to a show would be very much appreciated, as I need this show
for a piece of Uni coursework which will be marked as an assessment.

Thanks.
