Update... tried a frozen feeder of the same source tonite, at first, she seemed interested, but once she crept in close for the "kill" she noticed something was off and lost interest. She last ate live the night of the 21st, so that's two live feedings since her fast, and two frozen refusals.
Have you tried warming the feeder with a hairdryer seconds before offering??
That rarely fails if some initial interest is shown ...
