PokerTracker

When I stopped playing yesterday just switched PT off, didn't change any settings.

Today I've started it up (no Windows restart first attempt) and it won't display anything under the Texas Hold'em tab, though the HUD seems to work (I tried it on 2nl zoom).

What should I try?

Please enable logging and restart PT3 and if you still have problems then attach the PokerTracker.log file to a Support Ticket so that we can see the error message you're getting.
