Hi, Mary Beth -- Many thanks for the update and glad to hear you are all set! Could you please share what did the trick so that others who come across this discussion in the future might benefit, as well? 

No big secret, really... I think the secret was that I was working from a remote location through a VPN... and what caught my eye in your response was the recommendation to work locally...

I suspect that there was some interruption to the VPN that caused the error...

Excellent, Mary Beth, and thanks for sharing that working locally resolved the issue. :)
