PokerTracker

Everything was working fine until last week. One day I was in the middle of 12 tabling SNGs and importing for hud and postgres crashed out of nowhere. I closed pokertracker, restarted the service, and started importing again. Shortly afterward it crashed again. I tried housekeeping on my database which I do pretty regularly(not sure if this would fix anything) and during housekeeping postgres crashed again. Any suggestions?

Do you mean the whole postgres service is closing itself down? No postgres processes in Task Manager > Processes?
