Yeah, Rick - if you can listen to your own radio program on your computer, you should be able to listen to Bert. You have upgraded to RealPlayer G2, haven't you? If you're having problems, stop at the Help forum for counseling.
I note that RealPlayer is getting a little tricky about their download pages. the players you pay for are easy to find, and you have to look a bit for the free ones. The link above goes to the cheap seats.
