Jason, thank you for responding so quickly.
I'm not clear: are you saying it is possible to connect SharePoint Design with a P1 plan (non-SSL) or that I need to upgrade to an E plan to get SSL so I can connect?
I just double-check with the following URLs:
www.falkensmazebbs.net/.../Forms
I still get the same error message.
I am attempting to connect as the Admin user.
Thank you,
Neal
