I downloaded LW 4.16.6 recently... and can not get not a single search result for any of the wide variety of audio files I tried to download...

Can anyone make any suggestions?

Thanks.

Is your LW connected properly (all green/blue connection bars)? If LW's connected, try the fixes below.

1. In LW go tools > options > searching > basic & check whether the 'show license warning' box is ticked. If it does, untick it > Apply > ok...see if that makes any difference.

2. Problems with the search

3. Delete LW's preferences folder when LW's properly closed. See point 3 here & also point 2 if you've used older versions of LW in the past (there could be a folder in either location).
Fixes for LimeWire
This will change all of your settings within LW's options, you'll have to go back through afterwards & reset things to the way you like them.

If LW Will Not Connect
If nothing there helps, post back with your system details

It worked for some time this morning... I really don't have a clue as to whats going on... it seems that my connection strength signal is not very high while it was this morning....

If your LW isn't connected properly, could you please give your system details so that somebody can help you

And did you try the fixes in the 'if LW will not connect' thread??

Could you please keep your posts to one thread (this one)? Otherwise it's confusing.
