If your result is true then that's good news. But it makes it a bit more confusing for me as to what the problem might be. Try deleting your LW preferences. But before you do, make a note of all your settings within LW b/c once you delete the prefs you'll need to reset them. You'll find them: OS X: /Users/your_username/Library/Preferences/LimeWire
Windows: C:/Documents And Settings/your_username/.limewire
Linux: ~/.limewire

Now see if that makes a difference.
