"I use a Mac, and I was having trouble listening to a few audio files on your site. I fixed it though. I tried a few different things, so here's a few suggestions that may help if you're having that problem.

"First, I downloaded 'Flip4Mac' software and dragged the icon into my hard drive icon. Then I got a popup asking if I wanted to use FIREFOX as my default browser (I picked 'Yes'), and FIREFOX was able to open up and play the audio. If that doesn't work, download Microsoft’s free Windows Media Player 9 for Mac OS X.

"I hope this helps."
