The Help feature in Dramatica Pro for Window, especially on Windows 10, is no longer by the current versions of Windows. This is a known bug. There are two workarounds available to you:
1. The first help solution is to access the Dramatica Pro help files online for you to access with your browser:
2. The second solution is a bit more complicated but can be more satisfying:
If you replace WinHlp32.exe file in the Windows folder with the XP version of this file, you can see Help files.
I have attached WinHlp32.exe XP version described in the link below (see "Method Two").
