I'm using Vista Home Premium and regrettably, SonicStage 4.3 CP is a right pain in the bum. Nothing but issues with it. I have spent hour upon hour to get the darn thing to work. Uninstalled/reinstalled it so many times and gotten nowhere. So when I saw your compatibility suggestion I though lets go for it - nothing to lose and I was right! It won't start at all in XP SP2 mode. Luckily I have an laptop running XP with no problems. So I shall stick with that for all transfers until Sony get their act together and release another update.
