Error message while playing a WMA file in Windows Media Player

Hello,
When I try to play a WMA file in Windows Media Player, I receive the following message:
"Windows Media Player encountered a problem while playing the file. For additional assistance, click Web Help."
When I click the Web Help button, I am directed to a webpage that tells me that I have encountered error code "C00D11B1".
Is there any way that I can solve this problem?
Thank you.
