I added a folder with many albums, with various mp3 formats, flac wave. The program crashed, disappeared from the desktop but appeared in the task manager. restarting did not work, I had to delete TAGTunes.tagdb in appData which allowed restarting the program. so far I’m on an earlier version which works fine. I will try to update to the latest version with the current database of my library and check if it works and if I can add new folders.
Thank you and best regards, great program, especially SQ
