View | Code-Live menu not working in v2017.1

I just upgraded my Adobe Creative Suite to Dreamweaver 2017.1.

The Code-Live view is now not working so I cannot see the Live View mode.

When I select the menu View -> Split -> Code-Live, nothing happens. The selection doesn't change, even though the menu still exists. It stays on Code-Design as shown in diagram #1 below.

Even the View -> View Mode -> Live doesn't work. It stays on the Design selection. Refer to diagram #2 below.

I found this article online: View live data in Live View in Dreamweaver

It says to go to View > Live View Options > HTTP Request Settings but there is no option in my View menu for that. Refer to diagram #3 below.

Any ideas?

Thanks,

Sally
