I am trying to Deregister a remote worker and getting the below error. Any help would be much appreciated:

"Gone status code received. Deleting agent.config and setting agent to disabled."

I know that seems like a success message but it shows up in a modal window with the title "Error" and the worker is still shown in the configuration utility. I have deleted it from the Cloud account and manually deleted the agent.config file it mentions and the worker still shows up in the list (although now when you click the gear nothing happens). I made a copy of agent.config before deleting and if I put it back in place I can again see the details when clicking the gear icon.
