Hi all, I had the same problem the light would go green for a few seconds then back to red, could sit all day pressing connect to no avail. I deleted .limewire directory, tips, disable auto start, etc etc and would fix for 1 day or not at all! After talking to others using the gnutella network with other programs like bearshare, it seems they have similar problems and they advised that I fire up Limewire as soon as I go online (first thing after dial-up), and this worked, If I surf the web, download etc first the run Limewire it fails to go green! So I disconnected, reset computer then went online then ran Limewire first and away it went! Maybe worth a try, it certainly seems to work for me.
