party poker crashes on me always

[bigt2k4]

It crashes within 5 minutes of starting up, alot of the time instantly. I tried reinstalling the application, but that didn't work. I normally play on prima without any trouble and just started to play on party today, but it has been constantly crashing. If I set its priorty to high then my whole computer crashes. I do not know what or how to correct this, any help?
