do you have multiple installs? if so, chech your add/move if using windows, make sure you only got one copy of Limewire installed. And do you have an Anti Virus scanner? and a Spyware removel program? if you have these then I strongly suggest you scan your hard drive for viruses/trojans/worms/spam. Limewire SHOULD NOT open or close on it's own. I would suggest you do a fresh, clean install of Limewire, just incase you got it infested.
