Windows Media Player - Server Execution Failed

Bought a BOSE SoundTouch 20 to play music outdoors. The SoundTouch currently can access your music library from Windows Media Player, iTunes or NAS. All good except WMP won't play because of a "server execution failed" error.

Tried to fix WMP - Media Player fixes:

• Uninstall/reinstall WMP
• Stop/restart Media Player Network Sharing Service - move files so WMP can rebuild
• Clean boot troubleshooting
• Re-registering jscript .dlls
• System File Checker - sfc /scannow
• Checked Events Logs

Suspect that upgrading from Windows 8 to Windows 8.1 might be the culprit.

Could go through recovery process to take the computer back to factory state. Frankly, I don't need the pain and don't have that much time.

Gave up and installed iTunes.
