Try these fixes and if no luck then you may need to post your system details. system details

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 LW's options, you'll have to go back through afterwards & reset things to the way you like them.

Dear Remoc
Thanks again for the help.
No the show liscence box wasnt ticked. Im afraid i dont know where the preferences or connections tabs are found??? sorry!
I am using a broadband connection. HP Intel/Pentium 1.40 GHZ 224 mb ram. Windows XP Home. I have 17.3gb spare.
I have run basic several times on this and another computer and downloaded a fair bit then the next time i switch it on it wont go so i thought id try pro and the same thing happens. Fine until i turn it off and it comes alive but wont do anything. Says it performing the search but never ever finds anything.
