DATHeader 3.0.9.1

[Steffen]

On initial start, the application shows an error:

"Error in modXML.ini.XMLRead
The path is not of a legal form."

with just an OK button.
Maybe, the tool tried to read an XML file of a previous version.
I think it should succeed in that, not fail, hoping that these XML files carry
a version number inside, so newer software gets able to read old ones.

After clicking OK, the "Preferences" dialog shows up unasked.
Funny: it shows a "License Type" dropdown box with 0 entries.
I anyway entered some preferences and then clicked "Save".
Another error shows up:
"Error in procedure cmdSave_Click of Formular frmOption
The process cannot access the file
C:\Users\xxx\Documents\datheaderini.xml
because it is being used by another process"

However, there's no other DATHeader instance running, just this one.

Each time I click "Save", this happens.
So my only resort to close this dialog is clicking "Cancel", but then DATHeader crashes:
