Lime wire stuck at starting connection

This is taking place for about a week. I did not change anything in my pc, I did not install any firewall, I did not mess with lime wire's settings but for a mysterious reason it won't connect. I read similar threads but they did not help at all. Please if anybody knows what I should do, then give me a hand, but please don't ask me anything about ports, firewalls and etc cause I did not change anything and it worked a week ago and now it wont connect out of the blue.
Anyways I am running on windows xp,
I have no firewall,
i have de-activated windows firewall,
i have a 6mbit/s connection and my internet provider surely does not block p2p connections cause I use effectively other p2p programs (u torrent for example)
