Add a Trusted Certificate errors out

Greetings!

I have broke my server certificates.  I have not been able to receive emails from computer which are not part of the domain.  Its been a while and I would like to finally get this resolved. I am able to recieve emails outside of my network if I have added a computer to my domain.

So I did some research and found the problem to be my certificate.  So I went into my mmc.exe/add-in --> certificate ---> and in my drunken brave moment started deleting all of the certificates I created in the past trying to resolve this problem.  After doing this I went to removed my current resigned my certificate with Godaddy.  And attempted to reissue the certificate within the console... After this I wanted to install the certificate and went to Windows SBS Console, Clicked on Add a trusted Certificate and BAM!!!  I GET THIS ERROR MESSAGE.
