Are you running at least 7.1 SP1? This (accessing configuration editor over SSL) was an issue in MR1 and prior and was resolved in SP1.

Otherwise, have you tried resolving the Certificate Error you see in the browser? I imagine you have used a self-signed certificate in IIS per the KB you linked. Is that self-signed certificate installed on the computer you're using to access the console?
