Mbox Pro 3 not receiving audio from computer after firmware update

[Electrochemical]

I recently updated my Mbox Pro 3 firmware, and upon doing so I can no longer get audio out of it. The computer itself indicates it's playing audio, the Mbox control panel claims the hardware is connected and streaming, but the control panel doesn't seem to be receiving any audio. None of the various outputs or mixes show any levels.

So somewhere between Windows 7 playing the audio and the Mbox itself there is a disconnect. I noticed that prior to the firmware update, within the "playback devices" menu of Windows it had the Mbox as a single selectable option. After however, it now has split into 5 different options (speakers, S/pidf, Line 1/2, Line 3/4, Line 5/6) I've tried all of them, and within that menu it appears to be sending audio, but again the Mbox Control Panel doesn't show anything.

It seems that some have had this issue as well but I haven't been able to spot a solution. Anyone else have this problem? Thanks!

I solved the problem by uninstalling the most recent update and reverting to the initial 1.0.10 driver.
