Whenever you need to delete all files for a Brand or BookID, you should do this using the Tools menu Edit Song command. There is a delete "multiple" KMA files in the Select Multiple tab.
When you do it this way, the Songs Database is automatically updated for you.
By deleting the files directly from the hard drive using Windows Explorer, you now need to go to the Tools menu, and run the Build Songs Database command at the bottom. This will remove the files you deleted from the Songs Database.
I trust you will realize the Edit Songs command is far safer and easier to use in the future.
