Singer's CDG's won't load on playlist

[janskips]

I purchased the laptop and Hoster program. When I first received it, I tried a track from a cdg. I couldn't get it to work and decided I didn't know enough about the program yet. I proceeded to download approximately 13000 songs and became more familiar with the manual and am ready to start running our karaoke shows from the laptop. However, the cdr drive will still not read a track from a cdg. (clean, brand new, old, scratched doesn't make a difference) I get a message that the "CDR/CDROM DEVICE NOT READY, PLEASE INSERT A DISC A TRY AGAIN." The CDR works for playing music, pictures etc on a CD; so is it link between Hoster and the drive that is the problem? Janis
