Candle crashing after loading g-code

[Rustylj63]

I'm quite new to the whole CNC world and am suffering incredible frustration trying to figure all of this out. I'm using Vectric Pro 12.010 on a Genmitsu PROVERLXL 6050 Plus with a 4th axis rotary device. I've created what I think is a fairly simply toolpath for carving inlays for pool cues. When I load the g-code candle opens the file, starts to load the file, then upon completing the load candle simply crashes. The program shuts down. I have set up the following post processor in Vcarve Pro: Grbl (inch) (*.gcode) Can someone please help me get the help I need? Thanks!
