Hi . I checked and it seems I do not have a setup anymore.
Now thinking about it. I think this could have happened because I got the update now message so I clicked thinking it would update automatically, but when I noticed they brought me to the website where I had to newly install calibre I cancelled and then when i came back all my books were gone.
Does this mean I should have my old setup preferences somewhere?
eta: I checked and I see to my delight (I think) in my calibre files in explorer the normal metadata one but i see also one metadate pre restore. It is only 127 kb though while the other one is 3963 kb
