I too have the same problem - my operating system is Mac OS X (panther) and I have downloaded the lastest version of limewire pro (3.6.15) and the top of the tool bar reads "LimeWire: Enabling Open Information Sharing (Disconnected / No files available) so I go to File and click on Connect. This causes the Red button on the bottom left of the window momentarily to turn to green before reverting to red. I have restarted the computer (actually computers - I have installed on both a G4 Powerbook and a G4 desktop). I am stumped to know that to do. Please assist.
