Also, just to clarify, you're moving from a WordPress.com site to a WordPress site that's being hosted somewhere else, not from one WordPress.com site to another WordPress.com site, correct?
If your new blog is still hosted on WordPress.com, you should reach out to support here: http://en.support.wordpress.com/ . WordPress.com and WordPress.org are different flavors of the same WordPress, but still different enough that WordPress.com support would be able to help you a lot easier.
