Program error - brightness/contrast
I am using Elements 2019 with Windows 10.
In expert mode using the smart brush tool I am trying to enhance the brightness of part of an image.
The brush tool is fine but when I select enhance, adjust lighting I get the following error message:
Could not complete the brightness/contract command because of a program error.
I have tried on two different devices and get the same message on both. I am working with RAW CR2 images but have also tried with a jpeg of the same image and get the same message.
What is causing this and how do I resolve it please?
