Connection Problems
 

I've been using LimeWire for about a year with no problems. Starting yesterday, my "search" comes up empty. I haven't changed any settings, nothing is new, same computer, etc. Does anyone have any suggestions? I'm using Windows XP, it says I have a strong internet connection, LimeWire has not detected a firewall, I've uninstalled and reinstalled LimeWire, rebooted---I can't think of what else the problem could be, especially since it's worked fine in the past.:( Any suggestions? Thanks!

If your LW connection is ok, try this: Problems with the search

And if that's no help, 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 kill all of your settings within options, you'll have to go back through afterwards & reset things.
LimeWire Pref Folder in Vista

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.
