Error in MesaCT 2.1.0

Hi all,I get an error message when I click on "Calculate Scale" in the scale calculator:
Steps/Revolution must not be blank
However, I have entered data in the corresponding field.
 
Can anyone help me? The version of MesaCT is 2.1.0

MesaCT has nothing to do with Pncconf. You might get better response here:
