This happened to me too. All my campaigns simply stopped running and the distribution setting on my ads now say 'not set'. I can't believe its taking them so long to fix this! Losing $$$ a day in revenue. I created a new account and replicated the campaigns and its running; but with nowhere near the traffic my old ones were getting before they stopped.
