I have been using LimeWire 4.0.7 for awhile now and I tried to open it and it gave me a LimeWire Launcher Error it says Sorry, LimeWire could not locate a suitable Java Runtime Eviroment. Please download and install one from http://java.sun.com/getjava/download.com

I have download the lastest one from Java Sun the J2SE Runtime Eviroment 2.0 update 1. I am have Windows XP
I have tried everything i can think of, can anyone help me?

Edit: I have uninstalled and reinstall both the LimeWire 4.0.7 and the J2SE and still says LimeWire Launcher Error it says Sorry, LimeWire could not locate a suitable Java Runtime Eviroment. Please download and install one from http://java.sun.com/getjava/download.com
