As of this morning reqRealTimeBars no longer seems to be working. No error codes, but just no information received. Anyone else having this problem?

Maybe not: IB does its monthly changes to data subscriptions pretty much "anytime during the first week of the month" so, they could've sent you a price change about something weeks ago, you let it go, subscription-wise, and they just now acted on the termination. (Which means, you could be 2-3 mouse clicks away from d-d-d-d-dataaaaaa. )
Which instrument? Are you sure that it was trading at the time? Don't forget that certain US instruments have an "extra" holiday on December 5th and stopped trading on December 4th due to this.
