Hi Gil
Sorry you're not having any luck with this problem, some people have reported the same thing and upto now I haven't seen an answer.
It is frustrating to see problems not addressed, I know. But most people on the forum are just users trying to help other users who are having trouble and they do it in their own time for no reward.
The developers don't patrole the forum every day, they don't have the time and believe me, I know how time consuming this can be, on a busy day I can spend 2 hours or more just reading. I think the life expectancy for a forum helper is about 6 months and we lose helpers all the time.
If it's not working for you, you may be able to use another gnutella client more successfully for now and come back and try LW on a future update. I'm trying Peerahna at the moment, it works well but it is very different and very new, took me some time to figure it out. You could try it and if you have problems, there are developers on IRC channel #gnutelladev, usually in the evening, European time, who may be able to help.
Good Luck Gil
