Here is the latest official PTS patch:
NOTE: Make sure you download and install the PATCH, which is the SECOND "Download Now!" link from that page, or your program may become unregistered.
Fixes and enhancements in this patch:
-PokerStars added "USD" in the game level of each hand history which causes incorrect game level descriptions to be added to PTS
If you have any game levels that have "USD" in the description then you will need to merge these into the correct level or else you will start having problems. To do this use the menu and select Utilities > Database Maintenance and Options. Go to the Misc. tab and use the Change Game Level... button. After you convert a game level to the correct level you should delete the level if it is still listed on that tab.
Another option correct your data: use the Utilities > Database Maintenance and Options window to purge these sessions with the wrong game levels and then reimport your hand histories with this latest patch.
-Ongame added support for their new R5 hand histories. See the next post for instructions on how to import hands.
-WPEX added Razz game support.
-Ongame fixed problems with negative and large rakes. You will need to purge and re-import your hands to fix the data.
-Ongame - format change, they added a rake taken line that was not allowing hands to be imported.
-Cereus - format change, they added a letter in front of their game number in their hand histories.
