I have the very same problem. Downloading all I want, but every single UL attempte get the message 'transfer interrupted'. I also have COX and a router firewall. I do have XP firewall, but I've indicated to allow access for Limewire, (I suspect I would have trouble downloading otherwise). Like you, I feel bad that I can't share effectively. I have over 2000 file to share! If anybody has a relatively painless solution, I'm all ears.
