Some users have reported an issue in which they are suddenly unable to play streaming Windows Media files from various websites. These include the Sirius and XM streaming sites as well as other outlets.
This issue can usually be resolved by simply setting Windows Media Player as the default playback program. This can be accomplished as follows:
- Click the Start button
- Go to Default Programs>Set Default Programs in Windows Vista (or All Programs>Program Access and Defaults in Windows XP)
- Set Windows Media Player as the default media player.
If the above process does not work, you may need to rename the folder “Windows Media” in%appdata%\local\microsoft then re-try streaming.
