Ive sussed it...
I think when my screen went all tamagotchi style funny the other day it was because my virus's USB blew..
It wasnt finding all the outputs in my cubase devices - only the virus external inputs and outputs.
Now it wont find the virus via usb at all, it says the hardware is busted when I plug it in (and yes ive tried every USB slot I have and many different cables)
oh well , time to sort out a trip to germany for it. Ive had it for a total of 6 weeks and has been used for about 6 days total.
fun
