--- Comment #12 from hangukmiguk on3.40.se7en@gmail.com 2008-02-02 14:19:45 --- Here's some of my research into this.
PokerTracker does not commit registration keys to Registry. They commit them to an Access database in the Poker Tracker V2 folder. The filename is ptregv2.mdb
So obviously, there's a problem reading from that database, which gives you the +0.whatever product ID that mismatches when you try to load a second time.
Hope that helps any developers get a sense of what needs to be done to patch wine to get this going.
