How do you fix radiosity core?

I have an error of “Light Transport” job failed with error code 10 (“Radiosity core is corrupted”).

I have one gameObject made with maya terrain with trees and water plane using Unity 5p3.

I have never been able to use lighting on unity 5, usually takes all day and then I get error messages for a simple scene of only one game object, direct light, wind, terrain, wind sound.

the same problem in 5.3.4……

Update your Unity version. The latest stable version of Unity (at this point in time) is 5.4.3.
