Can't Import from Blogger

I’m currently trying to import content from Blogger to a new WP site.

Here is the message I’m getting:

The page you have requested cannot be displayed. Another site was requesting access to your Google Account, but sent a malformed request. Please contact the site that you were trying to use when you received this message to inform them of the error. A detailed error message follows:

The site “http://domainname.com” has not been registered.

I found this issue in the wp.com forums, but was never able to find a resolution anywhere (even here.) Help anyone?
