Sorry, does not work, I have still the same alert on opening (64bit)... I have skipped the 2 first ones, because I tried that when the problem started, and changed the preference file as hinted by you. 2 new files have been created. as you mentioned (one on opening (intrface) and the MySet-up on closing the program), but no result... I am now going to sleep on it (in Germany)
