I have an hp pavilion with xp, and an amd athlon processor 850. I successfully installed and played madden nfl 2003 for a few months. Now the program is unresponsive. Double left clicking, right click open, autoplay, and add or remove programs are what I have tried to open the game, but nothing happens-no error message, just returns to desktop. I don't want it on my computer anymore because I have a 14 gb hard drive which is almost full (madden takes 650 mb). Please tell me I don't have to remove everything to fix this!
