Help installing CA certificate bundle from Symantec

I'm having a huge issue installing the CA bundle that comes from Symantec when you purchase an SSL cert for a site hosted from my 10.4 server.

The site profile I setup in the server admin GUI worked just fine - I was able to create a CSR, get the certificate and install it. However, Symantec has a CA bundle that has to be installed in the keychain in order for the encryption to work. This is where I'm having the issue.

All the instructions I have (including help from Symantec), say to copy the text of the each CA into it's own file, and name each one, primary.crt and secondary.crt. I did this by opening the Text Edit App, copy/paste from the Symantec site, and renaming the .rtf file as .crt. It then says to open the keychain manager and click - import in the file menu, and install each CA into the X509Anchor. Problem is, when you click 'view certificate' in the import dialog box, it's supposed to show you info about the CA you're going to install. For some reason, the file I created from the textedit app (with the .crt extention) is not being understood by the Keychain Manager.

Any ideas what to do here? Symantec support is useless, and suggest I post something here.

Appreciate the help.
