PokerTracker

hy everyone, today i find that when i open PT4, anny idea why that ?

Please update to the latest version of PokerTracker 4:

Download PokerTracker 4

Next reset that report by right-clicking on it and selecting 'Configure Report -> Restore to Default -> OK' and see if that fixes it. If it doesn't then turn on 'Enable Logging' in PokerTracker 4 via 'Configure -> Options' and then restart PokerTracker 4. Reproduce the issue and then create a support bundle via 'File -> Create Support Bundle' and attach the resulting file to a Support Ticket.
