At the time of the second abort, all I heard from the comm loop was
one of the flight directors calling for a halt.  Neither of SpaceX's
commentators didn't go into great detail as to what the cause was.
Even if the ground crew could have debugged the problem, there
wouldn't have been any time to fly as the available launch window was
nearly closed.

One of the space news sites I monitor indicated that Friday of next
week would be the earliest available day.  The details concerning that
were rather vague, so it might have just been a rumour.
