Hello I have just bought a MD-RH1 and I have Windows vista. I can tell you that sonicstage 3,4 did not work. First I installed 3,4 and that did not work, after that I downloaded 4,0 and that worked once but afterwards the program continued telling me about this problem: "The selected music file cannot be played back because the system information has been changed. Click OK to automatically close SonicStage and open the SonicStage System Information Restore Tool. (Error Code 0004e2e)" The Restore Tool does not help me. If anybody has any experience with this problem and know how to solve it let me please know. Herbert - Denmark
