DATHeader 3.0.24.0 Error Message on startup

[Philippe Hurbain]

However, it seems that the program is running normally.
Another thing I noticed is that I can't create the new license type (4.0) in the settings because the program says I can't change the license text.
Even a freshly downloaded version shows this behavior.

I also have the license problem, but at least if there is a valid 4.0 license line, DH keeps it intact.
