Thankfully, I've managed to find a copy of my old presets using TimeMachine backups.

I've pulled this back from October last year, and imported into FileBot.

My preferences are back and working now.

I never knew about the F5 console before - comes in handy

Thanks for the reply.

The upgrade was done about a week ago (approximately) and it was downloaded from the FileBot website and installed.

I've been using FileBot foe many years now, and recently it was updated to the version V5.1.3 (10185)

Tried to use it today, and the presets I created for myself, specific to my needs, has disappeared.

All I have now is
