Gnutella Forums - Limewire has encountered an internal error

Greetings; this is my first ever problem with limewire - below is the error message...limewire just sits there with 'Loading Messages' active, but nothing else works. Any advice would be great, thanks. I'm on XP Pro, masses of RAM, no internet connection problems at all.
