I've got that error myself from time to time.
Steemit doesn't play pretty with my browser (chrome)
When I receive that (and other errors) I restart chrome.
So far that has solved the probelem for me...Your milage may vary.

How did you power down? I have the same problem and I am busy for over an hour and I still can't power it down
