Thanks for your prompt reply but, I sincerely believe that the song that I downloaded was not copyrighted. First, it is a song that was composed almost half a century before. Since than almost every musician interpreted it. Some of these interpretations might indeed be copyrighted and some not. This is the common fate of very old and very popular melodies. Still, the total silence of LimeWire after selling their product is not nice. They should simply not pledge support for paying customer or stick to their word. This is not an honest commercial practice. By the way, I am a new member and can you help me in clarifying a question that I have in mind? What group would be the most suitable one for getting technical advice on viruses specially targeting LimeWire? Probably it would be better to post two dozen pages in such a group rather than in an "open discussion" group. Anyway, thanks again....
