Guide: Problems with Refresh / Deleting Tracks and Album Art from Music Library

 There are times when refreshing the Music Player library either won't complete (eg: after you've dropped the phone popping out the battery in the middle of a refresh .. or is that just me?) or deleted tracks and album art won't disappear from the Music library after a refresh.

These problems are often down to corruption of the library and  the only thing to do is to delete the library files and start over.  Even a hard reset of the phone won't fix this as the files are stored on the card / mass memory.

To delete the library files:
 - Ensure you can see hidden files in Windows Explorer:

Windows Explorer .. Tools .. Folder Options .. View

Select "Show hidden files and folders"

- Connect the phone to your PC using the USB cable in "Data transfer" mode
- Find and rename (or delete if you're really brave) files with names like:

E:\private\101FFC31\mpxv1.mpd
E:\private\101FFC31\pcv5.mpd
E:\private\101ffca9\harvesterdb.dat

(assuming the phone's mass memory / card has been connected as E
Note that the folder names may be different and the files may have prefixes - eg: mpxv1.mpd could be called abcmpxv1.mpd.  Basically, you need to search under the Private folder for any files that look similar.

If you rename files - eg: by adding a ".o" to the end of the name - instead of deleting them, you can always just change the name back if you find you need those files back.

- Refresh the Music Player library
This will take longer than normal as it's a complete refresh, but it should now work.
