Reply to Gig Emergy: channel 2 is playing even when fader is on channel 1

Playing at a gig right now and the VCI-400 is playing channel 2 even when the fader is all the way to the left. I can take the volume down with the volume fader but the channel fader should be working. Anyone have any ideas asap? I tried reloading my TSI many times and used older ones also.
