Same here. I'm going INSANE!
I'm getting the same error: "The page you have requested cannot be displayed. Another site was requesting access to your Google Account, but sent a malformed request. etc" when trying to import my blogspot blog into wordpress.org hosted on my brand-new Bluehost domain. (Registration information is current and correct, despite what Google seems to think.)
So...I opened an account on wordpress.com (chicsteals.wordpress.com) and imported my Blogspot blog directly (chicsteals.blogspot.com). But the importer changed all of the photos in my posts (all 3000+ photos except 2) to 300px wide, and my original photos are 600px wide. And when I import from wordpress.com to wordpress.org (www.chic-steals.com; by exporting the XML, saving on my desktop, and uploading to wordpress.org) the photos not only stay super-tiny, but ALSO remain on the wordpress.com site and are displayed in the posts (and yes, I did check the box for "include attachments" in the wordpress.org importer).
I can't use the Bloger2wordpress conversion utility app, since it won't work at all in Firefox, and in Safari it just grinds and grinds and won't load the final converted file - so I guess it's not doing anything either. So I HAVE to import to WordPress.com directly from Blogger.
Please is there a way to import my Blogger blog directly to wordpress.org that actually WORKS and doesn't mess up the photos? (and destroys the formatting of posts, and de-links videos from posts, which are 2 other things I'm experiencing now).
(WP 3.0.1; plugin 0.3, hosted on Bluehost.com and after 2 tech support calls to BlueHost they say they have no idea what's wrong with it. Or why my photos are compressed.)
