Room not available error, yet system works fine

I recently had to replace a ceiling mic at a customer site because of water damage.  In doing so, the firmware had to be updated in the Shure P300 DSP as well as the mic.  The system works fine, but the Room Not Available message shows on the start up screen. It refers to the P300 not being available as an audio device, yet it clearly shows up as the audio I/O device in the devices menu.  Anyone know how to make this message go away?
