S/MIME control isn't available

Anyone have any tips on how I can view encrypted emails from my web based email that I can access using a CAC reader?

I receive the following error when trying to open an encrypted email:


The content can't be displayed because the S/MIME control isn't available.


Any help and pointers will be greatly appreciated! These forums helped me after MANY hours trying to configure my CAC reader to my new MacPro.
