And you have PokerAce Hud configured to use your preferred seat? Options->Preferences->Poker sItes->PokerStars, 'Preferred Seating' tab?
The stats should shift after you are dealt into a hand and that hand has completed.
If they are not, enable logging, open PokerStars, play 30+ hands on a 'single' table then send me the PAHud.log file via the [url=http:/www.pokertracker.com/support/]Support system[/url] so that I can review your configurations and troubleshoot the issue.
