Cant load g-code into mach3

so… yesterday i was cutting fine. i have had the full license for mach3 for about a month now. just as i was getting things figured out mach 3 stopped loading my gcodes. everything opens up normally, i can move my crossfire around still with the jog keys no problem, but when i load a gcode in nothing shows up. no warnings. no picture… Nothing… What did i do wrong?
