Try this ;
start > programs > postgreSQL8.3 > stop service, then turn right around a start the service fresh. If it works before you continue with the Poker Tracker3 b14 install, reboot and see if the same thing happens. If it does, doe the procedure again, install b14, and tell the folks at PT about it.
Otherwise, download the version with Postgres again, install it, and set it to load all your existing
hands from the old processed directory.
The only problem with this is
you will lose PokerStars tourney results. You FT results will be processed as they are now coming along with logging on to FT.
If you are not willing to lose those
pokerstars results, then you have to go through the Poker Tracker forum.
