I'm having exactly the same problems as the above users mentioned. I have a MZ-N710 connected by USB to my Win XP Pro SP2 machine. The machine has been fully updated. I have not used my Mini Disc for about 9 months, it used to work fine. All of today it has been crashing when I have tried to transfer music to it. Sometimes it manages to do one track, but it never manages to do 2. I have tried Sonic Stage 1.5, 2.x and 3.1 I have also downloaded the Nt MD driver from the worldwide site I have also tried Real Player 10 Nothing is working, and now I have no music to play (I did manage to erase my disks). Please can someone point me in the right direction as to how to solve this?? Many thanks
