It may have had something to do with the USB cable connection. I couldn't print using USB and
Simplify3D. I also noticed that my USB keyboard was not working anymore. Odd?? I rebooted my PC, power cycled the UM2 and disconnected the USB cable from the UM2.
I have a print going now, sliced with Cura and printing from SD card. It's been going for a couple of hours now. I hope it makes it all the way through.

You should contact support (fbrc8.com does support for USA customers with UM2s). They are very good.
I'm not sure exactly what you mean so maybe a video would help. Could it be:
1) gcode file is empty or corrupt? Maybe slice another one? Try printing something that used to work.
2) Could it be the power brick? Some of those are flakey.
3) Could it be K1? When that gets stuck the controller works fine but the motors have no power and the nozzle/bed heat don't work. That would be at the "tune cancel" screen though - not the "print material maintenance" screen.
