I thought Chris had provided a link to a different stream, but could not find the message in which it was posted. Hopefully, he will log in with suggestions.
Which version of Windows Media Player are you using? You may want to try re-installing it or updating it.
I use RealPlayer, and we have a whole thread devoted to problems with that format, but TM seems to have found a fix. I rarely have problems with WMP when I use it, so I can't offer any suggestions on how to fix it. I click on the icon and it plays. I use it as a backup when RealPlayer is down.
You may want to send Chris a private message, he is the most likely to be able to offer suggestions.
