Do You for sure have the most up-to-date PT? There was a patch some time ago, which solves the problem of the game numbers - I'm not sure if it was included in the PT update also, so if You have this problem - look for that patch.
With it, everything works great - especially after the software upgrade some time ago. (altough it doesn't support tournaments).
LMOJ: in PT, when You open the auto-import window for Ongame sites, there is a button: "configure database file(s)" - click it and then choose appropriate database (you can select which one to use (or create a new one) ) from Mansion lobby options.
Furthermore, there is a thread concerning multitabling at Mansion by using ramdisk - it's a must for more tables unless you have some hiper-super-fast computer and hard disk(which is a main concern with their silly databases).
Hope this helps.
