Using Hoster 4.0 KMA files with Older versions of Hoster

[KaraokeJohn25]

Let me first say that i had trouble with Hoster 4.O on my laptop and I reinstalled Hoster 3.108 back on it and Like the way it performs. I basically could not get the MTU Certified CDG Player to work. For some strange reason on my laptop Hoster 4.O would not recognize it. I bought new version of Hoster and Certified CDG Player to be able to import some disks that would not import with older version of hoster.
I have since installed Hoster 4.0 on my desktop and along with the Certified player it is working. I still don't like the Singer display on Hoster 4.O, I am used to having a single screen that shows lyrics, and then shows singers names and songs that are on the show list. I definately don't like the Marquee feature and Having the screen split in three sections. I'm telling you this so you will understand what I want to do.
Is it possible to import files to a external Harddrive using Hoster 4.O & the new CDg reader, hooked up on my Desktop and then Play them using an older version of Hoster such as 3.108 or 3.110? Also will I need to rebuild the Data Base on the harddrive when I use That Hard drive on my Laptop? Can I Uust rebuild the data base for that drive with out messing up the songs already on the C drive where most of my songs are? Finally would It be easier to Move all my existing KMA's on C drive to The New External Drive and then rebuild the Data base? I am looking for a good easy solution to this query.
Thanks in advance for any help you can give.
