I've got the same problem going as well.  I used to use this
program frequently.  Now I'm at a new job and am behind a
firewall.  However, I've had no other problems with any
other software.  

I'm using port 8080.  I've got my proper id and password
entered in the proxy password.  And my proxy address was
provided by our tech. guys.

Despite all of that and no matter what I do I get the Bad
Gateway error and nothing at all is downloaded, regardless
of the website I'm trying to copy.  Here is the log file
generated in debug mode:
