John,
Try downloading and updating the ASPI drivers from:

One other thing to try, click on the Audio button, if the drives show, then its working, but your drives don't support the CD+G format. Or you can click on the Detect Drives button to do the same and it will tell you specifically.
This may help to fix the problem. The only problem is that the NEC drives won't do the CD+G format.
