Francois Thank you for clarification. Based on this:
Francois Affected faces were not reassigned to another face. Affected faces became unassigned AND were not being recognised as faces anymore
I suspect that you or some one else had accidentally rejected all those faces. Could that be the reason? One of the ways to do that would be to select several faces for the person and then press Control+Backspace, but there are other ways to to that, obviously.
The probability that thas was a software glitch is quite low. When something glitches, usually just one thing fails. But in ordrer to remove faces, so many things need to happen inside program, so it is hardly possible to be result of a glitch.
As I said, the result of that change is permanent, and it is already reflected in ini files, so actviating a license will not change that.
If you would like to have a fresh start, you will need:
- Uninstall Tonfotos
- Remove all ini files
- Install it again.
This will work both on free and commertial licenses.
