This is how I replace a corrupt KMA file.
Using the search function in Hoster, I search for the song in question
and note the DiscID and the BookID. In your case the name of the KMA file should be "XYZ0094-39.kma" with a book ID of "9439" and a disc ID of "XYZ0094".
I plug in my external drive that holds my backup kma files. Using Windows Explorer I find the "XYZ009-39.kma" in my backup folder and copy it. I then go to the folder on my C:\ drive where my main KMA's are located (using Windows Explorer) and find the "XYZ009-39.kma" file. I delete the "XYZ009-39.kma" from the C:\ folder and paste the copy I got from my backup folder. This will replace the currupt KMA file with a good copy without changing anything.
I hope this helps.
Jim
