Pogo.com/Java applet not working need help?

I am a member at Pogo.com and I can't play the games.I only can play for about 5min. and then a window opens stating that I do not have Java applet on my computer, but I do. I have to reinstall Java Sun like every other day so that I can play pogo games. I am trying to figure out or hoping some one had the same problems and solved that issue. Please comment if you had solved the issue with Java and Pogo.com website. I am a member and I do plan on canceling my account, but I truly enjoy playing the games on Pogo,because it helps relax me after a long day of work and etc. Please help!
