when i have finished downloading a song it disapeares,
where dose it go, how can i find it?

Well ... when I got mine, the songs didn’t disappear until I closed lime wire, so what I did was, I went to the start bar and went to search - for files or folders. Then I typed in the song title I was looking for, and it tells you what file your computer put the songs in. Then since I use win amp, I went to “add media to library”. I hope this helps!
