i am using vista(obviously) but when i try to search for a song on limewire, nothing happens. i dont get any search results. i am using wireless internet. i dunno if that has anything to do with it.

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's ticked , 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 nothing there helps, post back with your system details
