Hey i have recently downgraded from pt3 back to pt2 and acehud becuase ive started playing on the microgaming skin Unibet.

I have got pt2 to import and process my stats but getting stuck with getting pahud working. Right now it detects the table and is somewhat erratically throwing up stats. These appear to be of players who i already have hands of in my database. So if i have played 100 hands with player x they will appear on the screen however, as i play more hands the stats wont show on the hud. Also no stats are showing of new players at the table although i reduced the minimum number of hands required to 1.

You probably have a lot of old hands in the prima gamehistory.dat file - with PAH and Prima closed, use PT2 auto import window to force an import. When it finishes, use the 'Reset' button to empty the local gamehistory file. This will mean that it's much quicker to import from next time, and PAH will get to the new hands much quicker too.
Personally I do this at the end of every session after I've finished importing.
