I use Windows XP home and the latest Limewire Pro and have had no problem until the layout etc changed. I can download files no problem and do check to see the file extension etc, ie wma or mp3 etc and only download mp3 files, and check to make sure they're a decent size; 3mb etc and not ridiculously sized 100kb ones. However, any files search for download fine, but will not play. I use iTunes for all my 12,500+ tracks. I do like the option of the track automatically playing in iTunes, but mine don't. Why not?
