I am trying tosearch for music and it comes up as though it is searching but there is nothing there. My screen is blank, can someone help????

Is your LW connected (all green or blue connection bars)? If you're connected, try these fixes:

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 options, you'll have to go back through afterwards & reset things.

If LW isn't connected, please give some details.
