Thanks guys, I have now re-installed LW and am running my first search. I found the 3 links above really useful and have already gone into Tools and put them into practice. 5 mins later...I have had some success!!! One .mp3 file I've been trying to download unsuccessfully since last week has come in properly!! Another one wanted to run PLAY_MP3 again, but still, the results contain a lot less spam.
Much appreciated...
