I'm running Limewire 2.8.2. I share 9739 files. I can download just fine, but there are no uploads. When I run other p2p program, there are almost always uploads from me. What can I do to verify that uploads should work, and to find out if something is wrong?

I'm behind a Cisco 678 dsl modem/router. I have port 6346 forwarded to my machine.
