blank screen
 

Okay, so it lets me search for something. But then it comes up with nothing. It doesn't say "No Matches found". The area where the songs is just blank. Can someone help me???

Are you connected properly (how many green connection bars do you see)?
If your 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.

If there's a connection problem, please give us your details.
