Audition CS6 - Hardware Configuration Unable

Oh dear. I thought that all these absolutely awful Creative Labs cards had finally gone away. The ASIO drivers for them were noted for causing many faults and problems for their users, but you should have been able to return to MME without difficulty, I would have thought. But at its root, this isn't an Audition problem - it's to do with the MME driver. You will have to go through all the Windows sound settings to reset it, I suspect - it's likely to have been turned off or made unavailable. And unfortunately it's not a step-by-step thing we can do remotely, although Adobe's help desk might be able to - try giving them a ring?
