Did you click on the blue link in my last post & follow the advice?
If you're a leaf node shielded by an ultrapeer, that's no problem. Ultrapeers are people with a fast connection, who aren't firewalled.

There's no disadvantage in being a leaf.
Delete LW's preferences folder when LW's properly closed. See point 3 below (also point 2 if you've used much older versions of LW in the past...there might be a folder in either location).
