thank you very much for this interesting and detailed explanation.
I had no idea that version R is not stable and maybe that is the reason for some things that I cannot cope with.....okay, it is very likely that it is my inability and ignorance....
I will now find out what I need to back up, so that the hours I have invested are not all lost....
maybe you have a suggestion for a guide where I can read up on what and how to back up everything for a new installation...for example, how to back up the H5 room and light settings.....the addons .......etc....
thank you again for your help and the time you have invested
PS: big compliment for your work, it is very impressive what you professionals create and make available to us
