I wish someone would comment on this as I too recieve the same error. I am not behind a router that would give me the error that the KB explains so I'm at a loss. What's worse, is I can begin a download and everything works great, but half way through I recieve:
Code:
[13:05:42] 426 Connection closed: The specified network name is no longer available.
[13:05:42] Transfer failed.
