Hello,
i have a Problem with PT4. I importet a database with some Hands, (for some people >6k hands) but in the Hud the Stats doens't appear for the 6k Hands, but only for 20-50 hands.
I selected all DB for the HUD. Then I searched for the Housekeeping, but i haven't found it. Does it exist and do I have to vacuum, analyze and update the cache after an Import from Files from the HDD?

Housekeeping is no longer necessary - this is done automatically during imports.
One time when you may not see stats for all of a player's hands is if you play at different table sizes. By default PT4 shows you stats from hands played with similar numbers of players - see the "Number of Players Filtered" setting in HUD Options. If you're playing with between 3 and 6 players you'll only see stats from previous hands where there were between 3 and 6 players, for instance.
