Can someone please help?
I have recently had to reload windows xp and now my computer just wont except digi design as an audio engine
I have loaded my mbox with usb then my 002 using fire wire and still no luck.
When using window Media player the sound pays but continually drops out pro tools will load but only plays for a moment and then generally freezes the program.
Can some one tell me what is going on
