I purchased my HX Effects Thursday, February 22nd, I turned it on tonight for the first time. It booted up and came on fine and I used it for about 10 to 12 minutes. I turned it off. But when I tried to turn it back on It just says in the top three windows, Line 6, HX Effects, Firmware Version. Bottom windows are all black and no button on the unit will do anything. Please help? Thank You, Robert K. Raudenbush
