Franky, I did not try hijack a threat. I read: Tip: if you want to post a new question, first select the forum below, then post your question in it. So I looked for a similar thread to my problem (fatal error). I have tried to figure out to post something on the forum, but can’t see how this should be done. I still do not understand how I can ask a question in the forum.
Second, I have no idea why I had I fatal error when updating yesterday, and I do not understand anything of the error messages (I am just a user, not an programmer).
Well, indeed it must – probably – been a temporary problem as you suggested because today the update from version *.34 to *.39 worked perfectly well.
Thank you anyway for the answer
