In my last post on Nov. 6 I failed to mention several things that I have tried, but I have deleted both the .limewire and Limewire pref folders, reloaded Limewire and upgraded Java after the problems occurred. I have no problem with any other program through the router, and I downloaded a network mapping trial software suggested somewhere in here. No luck on any of those steps.
Read foolofthehill's response, which I assumed was to Buffy, but not sure. I didn't do the reinstall and upgrade in that order, but Java didn't seem to be my problem.
P.S. My previous post did not record my answer, but I am connecting from home.
