I am using an mbox mini with a macbook, it has been working fine. But all of a sudden logic won't record. I get nothing from either channels, microphone or guitar, so it's not phantom power, it's not mic/line or di/line switches. I can hear the instrument or microphone fine when I listen to what's coming straight from the mbox. But for some reason it isn't making its way into logic. Logic is set to the mbox and play back plays fine. I have checked input assignments and it seems to be in order.
Any help would be much appreciated, I am stuck!
