I ran the SMC installer. It tells me IVIAUDIO.AX has not been registered properly, but does finish.
Whenever I run SMC it errors and drops out a varying time after opening. Sometimes straight away, sometimes not for a few minutes (long enough on ONE occasion to actually use it to convert something to the Fuze - albeit with lip-sync issues about 20mins in).
I have run the SMC installer several times. That hasnt solved it, but then I havent changed anything so didnt expect it to.
