I am using New Blogger and am getting the same problem. I have tried everything I can on the Blogger end. I hosted on my own domain, moved it to a blogspot address, even exported and then tried to import the file. No luck. Am thinking that importing from Blogger won’t work. Wonder if I can export to another blog site, import there, then try to import into WordPress. Seems like a lot of work – anybody else found a workaround?
