    Default GrblGru error message

    Hi,

    I am new to this forum. I downloaded GrblGru V3.27.0 and tried to operate my CNC plotter. I tried to open a Gcode file with GrblGru but I get a error message "Object reference not set to an instance of an object."
    Could you please help me to solve this error?
    My operating system is Windows 7(32 bit) version. I use Arduino Nano with A4988 drivers for NEMA 17 stepper motors.

    Thank you.

    Fernando
