Jimmy, your post is a little confusing. You say you just started using LW, but now you want to delete it?? To properly delete Limewire go to Start > All Programes > Limewire > Uninstall. Then go to Start > Search > All Files & Folders then type in Limewire and delete anything that it finds. You also might consider using CCleaner.
CCleaner.com to clean up your computer.
