Sounds really strange. I am suspecting that you don't have write access to C:\Users\SS8556\.dbvis and all its folders.
I saw the ticket that you have upgraded to the latest version (14.0.3), that's good.
Please reply to the ticket if you have further problems.
When I run the program I always loose some connections, but only the last 1-2 added. I see just a placeholder "Database Connection" after proper db connection added yesterday .
I checked the forum and found only some retro thread to check the C:/Users//.dbvis folder, but nothing found there.
