Fixed!
Once I attached the external (USB) Drive -- Hoster opened up and allowed me to manuver --- had lots of fun -- Hoster didn't want to pick the file folder on the local HD that had the kma files on it -- It wanted to stay @ C:\ -- Finally let it build the database -- it said 'OK' -- But when attempted to 'add song' -- Hoster still looked for the external drive -- Finally attempted another rebuild -- it finally let me pick c:\hoster-songs. Now on the 'window' I have both my external as well as my internal locations (Had to delete the reference to c:\).
Guess this is a learning curve regarding having backups and how they will work.
Thanks for all the advice.
