I have been testing the TableTracker with PokerTracker 4.06.4 on Windows 7. I play at PokerStars and the client is always the newest version.
I get the following error message:
Unable to open table 'XXX'
Keep in mind that some sites are required to be launched through PokerTracker in order for the table opening to work properly.
You may also need to adjust the lobby filters at the site so the tables being launched are visible in the table list.
It makes no difference, whether the PokerStars client is launched through TableTracker - and whether the table filter is off. The error message is the same.
