Enable UPnP. See if UPnP works ok. That means your NAT firewall is still active but it allows programs such as LimeWire to communicate directly with this device to open the port it needs at the time.

Can you create a magnet link of the file & send it to me via personal message? Click on my username to send message. To create a magnet link, see How to use Magnet Links & Direct Connect

BTW do you see a brick wall in front of the blue world icon at the bottom of LW? If yes, that means the NAT firewall is probably the problem. And that's why nobody can direct connect to you. So try enabling UPnP.
