Evaluating

I would really love to use this software to produce my slide shows,
BUT i will not let me add music from my library to it. My music is
copied through Windows Media Player 9. I have pushed every button
and been on every page, I'm sure that it is something that I am
doing wrong because I am new to this, but if I can't make it work,
it does me no good.
Thanx in advance for any suggestions
Bev
