I have a Net MD Walkman MZ-N510. When I try to record music on a disc via USB I receive an error: ‘Could not find files to transfer’. The MP3s are available- I transfer them to other MP3 devices...no prob! I know it is a MD Software prob!! The recorder shows the PC--MD connection message on the LCD. I tried SS v4.3 – is there other software to look at? Is it time for me to pitch this technology? Where should I look to troubleshoot this problem? HELP!
