i have one of these and it works fine with sonicstage that i got from connect.com i have music that i downloaded from connect and mp3s... maybe you should contact sony to see if they can help you. also since you were bring the music in maybe do the add on for the mp3 converstion tool maybe the player is broke i had to reset mine once there is a button on the back that fixed it for me.
I just bought a Sony NW-MS9 off of Ebay. It didn't come with a cd, so I dl'd sonic stage from connect.com. I converted some files from cd to the player and it said "CANNOT PLAY". So, I cleared the memory stick and went on a search for an earlier version of sonic stage thinking that is what would be necessary. I dl'd sonic stage 1.5, did the same thing and am still getting the same message. Does anybody know what is going on/ what I'm doing wrong?
Any help is much appreciated.
Thanks,
Jon
