You can get ring game hand histories into poker tracker by exporting the hands you want from PlayCheck (our hand history system).
Select PlayCheck from the menu in the software and customize the date ranges or amount of hands you want. Then, once you've found the ones you want, there will be an EXPORT button shown. Export the hand histories to your desktop (they will be in text file format) and simply add to Poker Tracker

There are some revisions coming to the hand history system towards the end of the month, so we hope that the players will find it more user friendly.
As far as we know, GT is not compatible.
Hope this helps.
Kind Regards,
