Invalid digital signature on v1.6 DAX MIC Audio driver

After installing v1.6, I get a warning that the Kernel-mode WDM driver (DAX MIC Audio) does not have a valid digital signature and Windows is rendering the driver unavailable.

Subsequently, upon SSDR startup, a DAX Driver Error is thrown.

    Because we have updated the DAX drivers, we are using a newer digital signature. Windows Update should provide you with the latest ones-- have you done a Windows Update recently?

    I think that did the trick!  Sorry for the bandwidth but maybe somebody else will run into the same issue and this will help.
