I am setting up an Arduino 2560 with Ramps 1.4 printer. Once assembled I have been getting a killed printer halted please reset error. I made a video showing the setup, added Pdf of config, config adv and pins.ramps, and I have already contacted the manufacturer for advice. Any help is appreciated.

My Questions are
1) Why am I getting the Killed. Printer Halted, Please reset message?
2) Is there anything obviously wrong with the connections that can be seen?
3) What is the orange light on the Ramps board and what are the green and orange lights and green lights on the Arduino board?
