I assume you are using Beta 18? There is a problem where some tournament hands are imported as cash - if this is happening to you, you will see some strange cash sessions in the main application, and this would mean that you have no stats so nothing would show on the HUD.
yeah I am using beat 18 but the import works fine as I can see theirs stats in the Tournanment section. I experience this problem since the very beginning, only on pokerstars (it works fine on party poker for example)
I did choose stats for current cash limit & current tournanmentblind level the correct poker tracker database is selected the worth it is working fine on cash tables
If you have selected current limit only and your minimum hands is set too high then you will never see any hands. Bear in mind on quick SNGs you don't get many hands per level.
Check if the tournament hands are being imported as cash hands? We've been seeing a few cases of this recently, but I think it will be fixed for the next release.
