The only place to get Limewire would be at the official site I would think. I suggest then you uninstall that and download the free basic version at the official site:
www.limewire.com. Its the only site I go to for new Limewire releases. and I suspect you picked up a viruses as well. Limewire should not be shutting down or starting up at all on its own unless you got it set to automatically run on computer startup????
