No, I have not. My one and only account is the erh.germany one.
I saved two (master passwords, if that's what they are, since I did not give them a proper headline, unfortunately, for which I saved one as "old" and one as "new". I did not give a try with the old one, though. I will do that later this week. Can I come back to you, if I have further questions or infos?
Thank you so far for your willingness to help.
