Seems like either PsHandler can't find handhistory files or can't recognize (read) text in these files. If the problem would be related to assigning certain tournaments to theirs respective 'poker types', Timer Hud would show either "PokerType not found" or "Multiple Poker Types" (see: PsHandler > HUD > Timer). Please provide me with one of HH files which wasn't imported by PsHandler (send me via PM) so I could manually check if the problem is in the text recognition. And finally (most unlikely): try to remember what possibly changed related to HandHistory files (maybe windows language, some pokerstars settings, etc..) or PsHandler Settings.
By the way: in the picture I see PsHandler recognized and imported hand histories which created 18 tournaments with 193 total hands. Did all of the tournaments weren't imported during your new session or only some of the new tournaments? If all of the new session tournaments weren't imported, seems like something changed in between sessions.
EDIT: oh, I'm glad you've got it working
