iWitness not working properly after Party update?

[Robert A.]

When I run iWitness now after the newest party update, iWitness says that every table it opens has "-4" players on it and therefore after a couple of minutes of datamining it closes down all the tables and open 6 new ones with excactly the same problem. So when using iWitness I only get to datamine a few hands at each table before it closes the tables down and open up new ones.
Is there any fix to this problem? If not, is it possible to change the "timer" in the ahk-script so it will only check the current table and close them down after they have been open for lets say 20 minutes?
