Update to Version 7.0.1466 stopped and is stuck

I got a notice that an update is available and started the process but it never completed and got stuck on 3/3 almost at the end of progress line. My current version is 120826-0.

It says connection not established. but the screen is grey I cannot press anything. This happened to me before and I uninstalled and then re-installed but it happened now again.

Please help…
