here is a mail i just had with the PS support :
Hi, Today my poker tracker isnt working, i looked to see if everything was right, and i saw a subfolded of my name into my name folder (within PS/meoansey1/meoansey1) no Hands history there. >I was wondering (Given almost daily update of the client) how i could get ''as usual'' my HH back for a proper use of PT ?
Hello Francis, Thank you for your email and for allowing us to be of assistance. In our latest update, we fixed certain hand history problems our client was having with the new Beta Hand Replayer. However, we are aware that PokerTracker is not working properly after these changes. Unfortunately, we cannot fix this problem with PokerTracker, as it is a third party application not associated with PokerStars. PokerTracker should be aware of the problem and will issue a patch once they have resolved the formatting issues. Unfortunately until they do PokerTracker will not work properly with PokerStars.
