My Benmap version is 184.108.40.206. When I was trying to add population data, the OK box is staying inactive even after I validate the data.
The screenshot is shown below.
I have contacted the email shown on the website. The solution he gave me is helpful: Go to the “Tools” drop down menu on the main BenMAP window, select “Options” and uncheck the “Require Validation for Data Imports” box.
Just sharing this problem and solution with you guys.
