I think that I am having the same problem - I have just installed sonic stage 4.3 onto my vista machine and no matter which way round I open it (before attaching my nw a3000 or after it) the programme freezes and the vista error options come up - to either close it or to look online for the solution (which if you click it doesnt find anything). I have used sonic stage before on Xp and had no problems and my boyfriend uses it on his pc (which is vista) with no problems so I dont know what is wrong with mine. Any thoughts? Ax
