Is there an update for the Events+ add-on "Next Event Countdown"? It suddenly stopped work

The Next Event countdown extra of Events+ suddenly stopped working.
The shortcode does not even show in the viewed source code of the page.
(using Responsive Pro theme)

The parameter being used is,
[next_event_countdown format="dHM" goto="#" class="countdown-class" type="flip" size="70" add="0" expired="Too late!" title="yes"]

Tried using the base parameter of,
[next_event_countdown]
Still nothing.

Any ideas for a fix?

Sincerely,

Anthony M Power
