Calibrating accel in pixhawk - mission planner - no response

I did calibrate this pixhawk out side the plane when i first got it, but now I cannot get any response in the mission planner when I try to calibrate… it says “command received:” then nothing happens… please help… thanks

I finally got his to work by installing the latest copter firmware, then re-installing the plane software… not sure what happened but in case you have this problem, this might fix it.
