Importing Root CA and Personal Certs into TC8000 with Stagenow

I have a customer that plans to use SSL and we are trying to import their Root CA (.pem) and Personal (.pfx) certificates into the TC8000. I can manually add the .pfx from the security settings under the TC8000. I understand that you have to use MX functions within Stagenow to initialize the keystore and import the root CA cert into the truststore.  I'm getting errors in Stagenow and cannot get it working.

Has anyone tried this and have it working?
