LW attempts to connect, then closes up immidiatly?

[cmb9212]

Just recently i tried to open limewire and it did the little connection window and it worked. And then when the real limewire screen opens up it starts the uploading or whatever that is shows on the bottom of the screen with the loading bar. But after it is done downloading (i think its done) it closes up immidiately.
I cant get it to work at all, i tried completely disabling my firewall and the same thing happened, i also tried enabling my UnPn thing and it still doesnt work. When i try and open it it makes the little limewire thign on the bottom right by the time, and makes another one every time i try and open limewire again, but when i go to click on them they dissapear.

Why is it doing this?
