Hello, I am having exactly the same problem. I have tried the recommendations above, but my Device/media is still not being recognised by SonicStage. I am using SonicStage 4.3 and have a Sony NWA3000, I had been succesfully transferring music from SonicStage to my mp3 for some time (since September last year), but for some reason it has decided to go tits up on me in the past few weeks. I have tried to remedy the problem with the following: -Initialize disk -uninstall/re-install SonicStage 4.3 and a few measures mentioned previously in the thread. Frustratingly SonicStage is still not detecting my NWA-3000!!!! Also, I am having a problem with SonicStage itself, whenever I try to Exit SonicStage, the program itself does not shut down completely, and if I open Task Manager, it can still be seen to be running (and taking up 90%+ of my CPU). I believe these problems may be related but I have no idea how to fix it. Any help with this would be great thanks! I am getting desperate here!!
