If you want help on this forum, then you need to answer questions already asked of you: System details - help us to help you (click on link). Without these details we can't help you much. We don't even know which Mac OSX OS version you are running.

BTW for the earlier version LW: http://www.gnutellaforums.com/265025-post48.html. But you would need to delete your LW prefs folder first, otherwise the older version will behave very oddly & not as well as it should. It has different behaviour to the newer versions.
