When Hoster runs, the last opened Playlist automatically opens. If any songs in the Playlist are on a drive(s) that is not found, a message now appears showing the missing drive letter(s) so you are aware of this. Hoster then opens and shows UNAVAIL status for songs in the Playlist from the missing drive(s). You can close Hoster and plug in the drive(s) or continue without the drive(s) available. The primary reason for 5.05 is to restore merging duplicate BookIDs, which was omitted in 5.00.
