I ran into this problem, but found a resolution. This was occurring on two machines, one licensed, one free. Both were stuck at 1.0.1570, since 3/22 AM on one, and 3/23 AM on the other. Looking at the logs, I saw a HTTP 503 error when it tried to go to a Keystone something. My other internet stuff was working, so I hadn't expected any trouble, but I'm on satellite internet, and weather has been horrible, so I tried a power-down reset. It worked.
Never underestimate the value of the Big Red Switch!
