Hi Bentley,
I am a military personnel, have been having this same problem for the past few weeks now, was in state and now stationed in Germany.
Presently, I am doing my Master's degree, I called my college on many occasion, but they don't have a clue why I should have that error as well. They seems to be making life hard for me and told me series of technical problem with my computer or my ISP.
Since no help was rendered had to purchase a Hardcover textbook, so I took it upon myself, so had to come to your "USER to USER" forum.
All I did was what you enumerated, and It worked. Oops!!
Thanks very much, maybe your management needs to enlighten the so called college/university help desk. They don't know what they are talking about and stop pretending they are good at their job.
Many thanks.
