Using Hoster 4.11, I recently reorganized the files on my external hard drive. I moved my .Kma files from E:/Kma to E:/MTU/Kma, rebuilt my songs data base now when I open Hoster all my previous play-lists show the songs as unavailable

Now if I open Hoster 34 which I still have on my computer it still opens any of the existing play-lists.
The songs all come up and play by using the search fields or book ID entry, it is just all the old play-lists.
I was reorganizing my folders to be ready for the new version 4.20 which will have .kmh files as well so that I will have them all under an MTU folder.
Has anyone else noticed this ?
