I created a blog under wordpress and purchased an upgrade at the same time. After completing my blog, I created a domain name. I can't get into my domain name (user name and password) to move the content of my blog into the domain name. It won't let me use the same user name and password as the blog and I wasn't given any instructions on how to create that when I purchased the domain name. Help!!!
My blog url is listed below. My domain name that I want to place the blog content into is http://www.happybirdscraftinghaven.com.
