Help, I'm not very technical so I need some simple help.

I have windows xp and previously had limewire and had no problem, now, I can';t install my new one, it keeps telling me that a previous version is running. I have tried to uninstall the old one using remove/add programs, but no go. I did the search thing and found lots of limewire files that I tried to uninstall but they wont go, and I'm not sure how to use the cleaner to make them go away.

Any help, or ideas

Won't work
