I have a MD - MZ-NHF800. I have sonicstage 3.3.03. I have several MDiscs and now I Want to store them in my Ipod or make a cd. I don't know what's happen because it gives an error. It says the selected track was generate from another computer - false - and the code is 000065c7. How can I transfer back to the computer all the musics I stored in Disks????? Thans
