Alright I just tried plugging in my guitar to my mbox mini 3g and it's not getting any signal. Also, its phantom power isn't working. Not sure if this helps shed some light on anything. I'm going to try installing the drivers on my macbook and plugging the interface into that and see if I get any life out of it. If it still doesn't work I'll have to buy an ASC and send it in
*EDIT*
My interface isnt responding to my macbook either. Can anyone tell me how I can get a warranty covered repair, my ASC expired, but I purchased it less than a year ago. I'm having trouble getting in contact with a live person without an active ASC.
