[SOLVED] U-Mix Control Pro 1 - Volume Issues

Please forgive me if I'm missing something obvious here, but I do have a confusing problem with excessive volume.
Yes, I have read the manual, but it didn't seem to help with my particular issue.
At my gig last night, it took a while to get the volume down to an acceptable level, using the master knob on the Control Pro, but I had to turn it almost to zero to do that. Also, the red led was constantly flashing, which I understand means that there was clipping.
I checked the U-Mix Control Pro volume control (in system tray) and reduced that to about 70%, but it had very little effect.
I didn't want to experiment too much in a room full of people!
I just have a few little questions that I hope will be easily answered
1. Do the gain knobs affect the signal coming into the unit, and would their use reduce the clipping?
2. What effect does the program in the system tray have? Does it actually Control the volume of the Control Pro itself, or the volume going into the controller?
I'm sorry if these are silly questions!
