I am sorry for coming back to the same issue. I have again problems trying to move my project between my two computers.
I am now trying to move the images back to my laptop. I logged on to my laptop and opened Tropy, I got a message on my macOS that the versions were not in sync. I clicked on the last version. Unfortunately I think that was the old laptop version. Everything I entered in my macOS has now disappeared. How do I get the images I have entered on my macOS back?
