can't connect or shut down program - no firewall...
 

I'm on Mac OS 10.4.10 and have never had issues with Limewire unti today. I can't connect at all, I have no firewall, am not doing anything differently than I ever have, and I can't even shut down the program without force quitting. I just upgraded to Pro yesterday and it worked fine then.
Ideas?
