PokerTracker

i have a pc with 2 OS, win7 and win xp
i want to put PT on win7 too...i've reinstalled the poker client and PT in the same directory, and then i've copied all the files, to keep datas, options ecc
pokerstars works with all my configuration, but PT3 when it starts, it says that it dowens find the database...how can i do??

You will also need to manually install the exact same PostgreSQL on your second operating system, in the same location. If you're using the same folder structure then I think the same database should work in both operating systems.
