M1HD Crash

Please help!!! lol

Today my M1HD internal display locked up on me. I had all external displays unplugged. It froze to the point that the time on the top right even stopped counting. The desk itself was still resposive but I couldn’t see what bank I was on or select anything on screen. Had to reboot mid show. Now it isn’t showing up as a network show on my laptop (not connected when it froze) Running 4.2.1045.
