PokerTracker

I was making some notes yesterday and It ended up crashing on me, sent the crash/error report back. Since then, the HUD works but no notes are being made at all. What would you suggest? I did back up my PT4 a few days ago but don't want to restore unless I have to since a lot of filters were made since then.

Do you still see the note definitions in Tools -> NoteTracker and are they still set to Active?

Yes, they are.

Double check to make sure the date setting on the Status page is set properly -- if it's set to only take notes after some date in the future, that obviously won't work well.
