Hoster ignores some KMA files

[rontoo]

I have found one way to restore these files but it is very time consuming. Hoster won't reimport any song from an affected disk (error says book ID in use please select another. But I can't change that field). The only way to reimport that works is: First delete all songs from the affected disk, then build songs dadabase, then import tracks as though it is for the first time. That would be OK but there are about 150 partialy affected disks. It will take forever this way.
