What's wrong with my postgresql8.4???

[Hatio Mar]

hi,dude

I used poker tracker4 normally for several days. But recently, when I open pokertracker 4,it showed that

"Unable to login to database(postgres).Reason:server closed the connection unexpectedly. This probably means the server terminated abnormally before or while processing the request."

I have tried:1.creat a new databass 2.restart databass 3.reinstall postgresql8.4
But they all help me nothing. I don't what is wrong. Seems I have to reinstall my windows xp, but I really hate that. Anyone can help me?

Thanks so much!
