Mood:  don't ask

I am really hoping this is the right place to ask this. Is anyone else having trouble with creating subdomains?

I had a domain (and a subdomain), but decided today that I wanted my domain to have a different name. I bought a new domain, parked the old one (along with the old subdomain) and the new domain is now up and working. I want to create 2 subdomains (I am allowed 3), but each time I attempt to create one, I get nowhere. The page just refreshes and wants me to enter the subdomain name again. It never takes me to the page where I am to link a directory to the subdomain.

Long story short, no subdomains are getting created and I am getting very frustrated. Am I the only one with this problem?
