Try turning the device on before connecting it to your computer

If this installation CD contains a software in order to put your music on your player, then you don't need it. You just drag your music files onto the player using Windows Explorer.

Good luck, and Happy Holidays.

Hello
I had the same problem.
I suggest you visit this link and sony's esupport site where you can download an MP3 file manager.

I hope this works for you

cuando le voy a pasar la musica, y desconecto el walkman bean sale en la pantalla not invalide como ago para solucionar el problema

you have to transfer the music you downloaded to a new folder in sonicstage. From thier you should be able to put your music on a playlist in sonicstage. From there, you have to press the big red arrow in the middel of the playlist and mp3 player memory to transfer the file. I should all be found in the main screen of sonicstage. Now try that out.
