If you have problems with the application, I recommend you install the latest version from the developer's website. If you have an older one installed, this procedure should restore functionality. Additionally, other programs might cause a conflict between these apps, therefore, close all the applications and then install the latest version. It should work normally.

On a side note, turn off your antivirus or add the program to the Exclusion list to avoid possible crashes.
