Yes. You could try phoning Rapid Rewards and asking politely for a favor.
I was part of their glitched early sign up. Booked and rebooked more than a dozen flights on the 17th. 18th rolled around with the new terms of the promo. Had to call CS, and the guy helped out by rebooking all the flights so that they qualified for the promo. Pretty good service, although my email was bombed with notifications.
