I'm having the same problem. I did see one person try to upload a couple files from me, but both uploads failed. I loaded Gnotella on the same computer and had hundreds of clients successfully uploading from me. It almost looks like LimeWire has decided I'm an undesirable client from which to upload, which should definitely not be the case. I'm on a cable modem with 384kbps upstream.

I am behind a firewall, but I can configure the firewall any way I want. Does anyone know if I need to do anything special with the firewall to get it to work right with LimeWire? I already have ports 6346 and 6347 being forwarded to the LimeWire machine.
