RevOnlline Viewer connect problem

[Ray Stace]

I have asked RevSupport the following question, without luck so far, and
Jacqueline suggested I also try the group: maybe someone here knows the
answer...

I have updated to Revolution 2.5.1, but cannot get any network connections
to work from within Revolution [revOnline Viewer] so cannot access any of
the channels in that utility.

RevOnline viewer says ³There was an error while contacting the server.
Please ensure that you have an active internet connection, and try again in
a few moments.²
I do have an active connection.

RevNet says ³Check network connection and proxy setup in Preferences².
I have set up proxy correctly, [HTTP proxy: proxy.uow.edu.au:8080].

Computer setup:
Mac OS X 10.3.7
Revolution 2.5.1
Yes, I am behind a firewall, but all other network connections work
correctly with a variety of browsers.

Why can¹t Revolution connect?
