Please contact support so that we can log the issue and get you up and running. There is currently a known issue with Zoom that occurs on every other power cycle. We are in the process of fixing that issue as soon as possible. Regarding fader positioning, Ableton uses a scaling that goes to +6 dB. The FaderPort's scaling goes up to +10 dB. This is why you see a discrepancy in what is in the software versus what is printed on the FaderPort.
