I have the BFSR41 router too, supporting an I-mac as well as my PC. Limewire 2.44 on the Mac doesn't require any special tweaking to download or upload. The PC has version 2.65 on it, and I can't upload. The Shared Library folder shows lots of hits on the files, but nothing shows in the Uploads portion of the Transfer Window. And I can't download very easily either: the download area has everything cued up, but not loading. What can I do? I have a cable connection, and the default settings for number of connections.
