I wanted to edit my message here, but there is no function. I’m not sure about that “but at that moment I was doing it in a different way by moving the database”
and maybe I transferred hands from the laptop to the computer in another way (it could be text files with hands received from the poker room). But I got errors when I loaded some of the hands that were already in the database.
Perhaps you should be careful not to duplicate hands, it seems I got error in my database because of this, but at that moment I was doing it in a different way by moving the database (I did it 5 months ago and now maybe everything is fine or maybe I screwed up myself that time)
