The missing tables hm...
It's a bit bitchy to capture all because through an update by the pokerclient some may get lost.

What also helps is to apply the pokerclient filter to minize the tablelist.

I am not sure but isn't it possible to query the Database in Pokertracker itself and export this playerlist to a cvs-file?
You can import this csv-file into SpadeEye:
