Adding Zone problem

Updated 1207 formaware into NX-4. Cannot get a Dylos zone created. When I add a Dylos Zone using add Zone Fixture, I get the Enable Dylos Support, which runs, but that is all. It seems like a constant loop. Enable Dylos support.
I cannot create a Dylos zone at all. I have rebooted the console between enabling Dylos Support.
I have Factory content installed. But cannot get a zone created.
Has anyone else seen this?

Try a new showfile?

I reloaded the 1207 firmware and the issue is resolved.
Perhaps a faulty upload.
