Log4OM

Hi all, my name is Stevan, call sign YT2SIN from Serbia.
I've done something stupid and now I don't know how to undo it and I need help. I imported the log from the recent EUHFC and as I always do, I wanted to mark contest QSOs in the comment. I've done that in QSO manager/single field update, same as many times before but this time I haven't noticed that all QSOs in the logbook are selected... So now all previous comments in all previous QSOs are overwritten... Is there any way I can undo this???
Thank you!

Did you try reverting to your earlier backups?

You could use QSO manager single field update to 'Clear' all data from the comments fields on all QSO's but that wont restore the original comments, backups are you best safety net
