I searched for an old song and it works. I tried downloading the song I want from another person and it still didnt work!

If other songs download ok, there's nothing wrong with your LW. If it's a really new or really popular song (don't name song titles please), you might see fake files for ages...until someone shares the real thing. Keep searching at different times of day, as people log on & off the network files available for download will change. In this case, it's just a matter of being patient & perservering with the searches.
