Hi,
This might be because of the corruption in Windows Media Player. Let’s try rebuilding the Media library and check if that helps.
** Shutdown windows media player.
** Stop the media sharing service. Go to Start >> Type in Services.msc in start search >> Right-click on the “Windows Media Player Network Sharing Service” and select Stop.
** Navigate to “c:\Users\”your username”\AppData\Local\Microsoft\Media Player. Now delete the files named CurrentDatabase_***.wmdb and LocalMLS_*.wmdb.
** Start the media sharing service.
** Now start Windows Media Player and watch it build up your library again.
