Hoster Won't Access External HD

[JBass43]

I have at least a dozen folders under G:\Karaoke KMA Files\.
Each of those folders have folders and sub-folders.
I used SongVerter to convert my MP3+G Zipped files to KMA files, and I Checked the boxes to keep the original directory structure.
I expected Hoster to read the main directory (G:\Karaoke KMA Files\) and all the sub folders underneath it. I think I can re-do the Songverter conversion process, this time into a single directory, if that is the right thing to do.
