MediaMonkey shows files as greyed out when the tracks cannot be played.

This can occur for several reasons:

 1. MP3 and WMA files cannot be played because the version of Windows used is Windows

     Windows Vista N, or Windows 7 N, which don't include multimedia components.  See:  

     http://www.mediamonkey.com/support/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=134

 2. It can occur because of various other audio plugin incompatibilities or because required

     codecs are missing.  See:

 3. The tracks are not accessible to MediaMonkey. Such tracks also

    appear in the Library > Files to Edit > Dead Links node. It can occur if:

   a. Files are stored to a removable drive that is not connected or to a 

      network location that is inaccessible. Resolve by connecting the drive 

      or the network.

   b. A network path is mapped to a drive letter (e.g. J:).  In some cases, this will not

      work correctly because mapped drives do not return Partition Serial Numbers

      correctly.   The solution is to use:

      \\ip _address\path (always works)

      \\computer_name\path (often works)

   c. Files have been moved outside of MediaMonkey and the File Monitor isn't

      configured to update the library appropriately.

      o If you have MediaMonkey Gold, select all the greyed out tracks and use

        File | Locate moved/missing tracks. This will find matching tracks based on

         filesize AND timestamp, or track metadata.

      o If you don't have MediaMonkey Gold, delete the old entries, and scan the

         location to which the tracks have been moved.

   d. The drive has been changed and the new drive has a Volume ID that differs

      from the old drive. To correct this, first back up your database and

      then try one of the following:

      o If you have MediaMonkey Gold, select all the greyed out tracks and use

        File | Locate moved/missing tracks.  This will find matching tracks based on

         filesize AND timestamp, or track metadata.

      o Edit the database as described at:

         http://www.plasticsun.com/GiantInternational/Misc/MediaMonkeyNewDrive.htm

      o From the command line, type DIR and note the Volume ID of your new

        drive (e.g. E552-A081). Convert this hex value (E552A081) to decimal 

        as follows: 

        -Run Calculator (calc.exe) and enable Scientific mode > Hex mode

        -If the first (or the eighth from right, how you take it) digit is 7, 

         just convert Hex to Dec.

        -If the first digit is 8 (including A-F), do the following:

         Switch to Hex mode

         Enter 100000000

         Press -  (i.e. minus key)

         Enter the SN in Hex

         Press =

         Press Dec (i.e. convert to Dec)

         Press +/- (i.e. change sign)

        -Verify the media ID of your old drive (using the DIR command)

         Use Systernal's Volume ID tool to modify your drive's ID:

 4. Files are located on drive A or B. To fix this remove the drive letter from 

     IgnoreDriveLetters=AB in MediaMonkey.ini. For the location of MediaMonkey.ini see:
