Have you changed anything in the week prior to getting the message?
Updated the firmware?
What GPS are you using?
Does the GPS have a compass in it?
Have you turned that compass off?
Are you using Mission Planner for your setup?

Something has changed in if it was flying OK.
Photos, details, a log, would all help.

Hi Mike
I did try to move to PX4 version, it is not working ( level horizon is upside down)
so I went back to ArduCopter.
Looks as the older version I had was 3.6.10 ( I have the old logs)
Now I can not get back to any working version.
No external GPS/Compass.
I am using mission planner and tried also QGC as well.
I feel like steering water.
