Lost a whole bunch of random settings ... very strange?

Now I don’t know what happened ?!!?
I was Cubasing around and did nothing in particular when I noticed some kind of something happened like a big jump in the program.
I didn’t think much of it but since then I’ve noticed the settings of totally random things are missing, dialogs have been reset, the list of recent projects are gone and so are a few Key Commands I use often.
So … what more has changed??? :open_mouth: :imp:
I don’t like this at all …

Has anybody a clue of what happened or does anyone else have the same experience?
