Can No Longer Record Audio With iMic

I've been using the Camera Connection Kit with the iMic to record audio from my studio via 'Line In' for months with no issue. A few weeks ago, my iPad stopped recording using iMic. It only records with the internal mic now, so the sound is garbage. The software company says it isn't their software that's the problem. Did Apple have an update (prior to latest release) that rendered iMic useless?

Without the ability to record audio in this fashion, the iPad is a useless paperweight for me.

Any help is appreciated.
