Sometimes files will download directly from magnetmix, you don't have to search for them...use the magnetmix link in the "Blank results page" link that I gave earlier.
Did you delete LW's preferences folder? There are instructions in that same "Blank results page" link.
What's the connection status of LW? Do you see any green connection bars in the bottom left corner, or are they red? If LW's not connected properly, it's pretty impossible to return good (if any) search results. Sometimes deleting the prefs folder is a fix, not always.
Do you see the firewall icon (brick wall in front of the blue globe) & if so, has it always been there?
AT&T are known to block p2p off & on. These threads below will give you some more idea.
