I'm not sure this is a connection problem, but i need help
 

I was using limewire a few days ago and everything was running fine, I try again yesterday and today and now it constantly freezes and if i minimize it then try to bring it back up the screen is blank. If i had music playing it will still play, but I think the downloads are stopping. I was wondering if this is a bug or a connection problem or something.... ne1 know? And if you do know what's happening, how do i fix this?
