Live calibration problem

What does the reset button do? I pushed it several times and still cant get it to live calibrate. ARDUCOPTER 2.8

The reset button only reboots the flight controller.

Thank you. I can not get it to live calibrate to save my life. I think it is my Windows 10, may take it back and get Windows 7 I have my Talon flying on my Open Pilot now, and works just fine. I relay think its my windows 10, because I could not load Libre Pilot on it. I loaded it from a old Vista and worked I just don’t get it.
Thank you for any input
