When I open LimeWire it says it is connecting but I cannot get rid of that little window that asks me if I want to update to PRO. I don't and now I can't use LimeWire. Help.

Ok, more specific. What happens is I open LimeWire and it does all of it's little things with the little lime window. It opens and the little window pops up that asks if you would like to update to PRO. But, it never goes away and when I try to say "Later" or "Yes" or "What is PRO" they don't work. Nothing happens. Is this me? I mean, should I just let it sit. Is it possible that it's too busy, the page hasn't fully loaded. I've waited a while before trying to get past this little window, but that hasn't helped yet. Is this specific enough? Is there anything I can do to help this? Thank you!
