Move songs created in KHPro into Hoster Lite

[Sharon]

Hi
I have searched this site but cannot find my query anywhere. I just bought the KHPro and created some karaoke tracks from backing tracks a friend had. They play perfectly in KHPro. I went through the manual for hours but can't seem to export out/import into Hoster Lite so I can use them with my other karaoke tracks. I seem to have KPR file extensions in KHPro, but no music, or it saves as a CDG or a WMA....I'm now very confused with all these file extensions....and I've tried just about everything. Also, the disc ID, track ID fields etc don't seem to let me put anything titles etc in them so I obviously don't quite understand that bit. When I did manage to get a track imported, it was 17 seconds long and just playe dcrackling sounds. Am I importing as the wrong thing? Any help would be much appreciated.
