Java causing a problem

Ever since I installed Java the "Paste Special" dialogs display Chinese charcters. I tried removing Java and restoring my system but nothing has worked. I had origionally downloaded Java because a program I wanted to run required it, but then it also would not run. By checking on their porums I found someone who said that they removed the Chinese from Java by "Hacking" it, he did not say how and I am still waiting for approval so I can join that board.

I thought that you all may be able to help me, I dont know what else to try
