Spider III 75 - While trying to turn off one of the ABCD button lights I pushed and selected just about everything. I finally figured out what to do but afterward I now have no function from the Drive knob. No matter what amp setting, preset or just manually adjusting the knobs I get no distortion at all.

I know you can disable some of the effects, is is possible to disable the Drive function? If so how do I turn it back on?

I've tried doing a factory reset with no luck. I restarted several times while holding down the A button - the display reads Factory Reset so I think I'm doing it correctly.

Any ideas?
