Well - not sure quite what is going on here but I think you should run sfc /scannow and see if that finds and fixes any corruption. Instructions for your OS will be found here....just follow the instructions onscreen. - Ric.

Hello, I am having the same problem but didnt know which files to delete until I found this at thisbleepingcomputer

It sounds like the media libraries have become corrupted.

Ensure that Windows Media Player is closed.

Click Start and type services in the search box. Click on Services.

Locate Windows Media Player Network Sharing Service, select it and click on Stop the service.

Click Start and type %LOCALAPPDATA%\Microsoft\Media Player\ in the Search box and hit Enter.

Select all the files in the folder and delete them.

Go back to the Services window and Start the Windows Media Player Network Sharing Service.

When you next start Windows

Media Player it will start automatically rebuilding your media libraries.

Hi Jimmy S.C.,

Thank you for using Microsoft Windows Forum.

As with any database, information that is stored in the database or the database itself can become corrupted. The Windows Media Player library database can usually recover automatically from database corruption. However, the database may become corrupted in such a way that Windows Media Player cannot recover the database.

   1. Click Start , click Run , type %LOCALAPPDATA%\Microsoft\Media Player , and then click OK .

   2. Select all the files in the folder , and then click Delete on the File menu.

      Note You do not have to delete the folders that are in this folder.

   3. Restart Windows Media Player.

 Note Windows Media Player automatically rebuilds the database.

If this does not resolve the problem, clear the Windows Media Player database cache files . To do this, follow these steps:

If you are running Windows 7/Vista, click Start , click

Run , type %LOCALAPPDATA%\Microsoft , and then click OK.

Select the Media Player folder , and then click Delete on the

File menu.

Restart Windows Media Player .

Note Windows Media Player automatically rebuilds the database.
