Sorry to hear you're still having trouble...I was very frustrated, too!
Just wondering, when you start up LW, do you see a brick wall in front of the globe? For some stupid reason, I do...the thing is, it goes away after a few minutes. I never saw the brick wall before, and haven't changed any settings.
Once I can get my downloads going, Limewire usually works fine. The hard part it seems, is getting it going. Try disconnecting and reconnecting. I've changed my listening port to something around 64000 (exact number not important).
Just curious...can people download from you? When I start Limewire, I can get even more frustrated because I see uploads happening with no problem while my downloads are incredibly slow or stopped.
Best of luck
P.S. It seems that some may be experiencing trouble because of a recent earthquake in ?Taiwan. I'm not sure how far the effects of this can reach.
