I now get a first idea of what all those messages mean...

No, but I'm not afraid of it. I am willing to learn and try, but I guess I'd
need quite a lot of guiding thru the necessary steps. So, if you feel up to
help me, I'll be glad to take the opportunity, of course...
(I have some programming skills from earlier times (COBOL) and know some
but at least the "basic understandings" are given, I guess.)
