I just updated to 5.5.8 and when I do a search for audio files it doesn't find anything. No matter the search terms are, I've tried very general search terms or very popular songs and I get no results.

If I do an "all" search I find some files, but they're all mov, torrent, or zip files, never any audio.

This is happening to me also!!

I uninstalled Limewire and put it back on and still getting the same!

Help please!! This only happened after I upgraded to 5.5.8

Check tips here: How to find music

Also, try deleting your LW Preferences folder whilst LW is closed; instructions here: Point #3 in Fixes for Limewire (sample image included 2nd last post of page.)

I'm not sure what I did, but it's working now. Seemed like the next day it was back to normal!
