importing tracks on sound choice 8704 cdg

[prober]

On this cdg only, I cannot import tracks. Keep getting message, unable to read audio sectors, "Illegal command request (04h 00h 02h 05h 64h 00h).

when I first tried to read tracks, only one track came up for a second and dissappeared. then all 15 tracks came up. tried to import tracks individually, but get same message on all tracks.

Closed microstudio and removed cdg and started all over. didn't get the first track for a second, but still get the same message.

tried sound choice 8951 and it showed the 16 tracks, and by deselecting the 16th track, I could import the 15 tracks.
