I'm trying to move a blog from WordPress.com to a standalone WP blog. I've exported the posts and attachments without any problem, but when I try to import them into the new blog and the import file attachments, mapped to a user who already exists, the process stops after only one or two posts and then sends me to the blog's 404 error page. Every time I run it I get one more post, so I know they're in there.
Here's the new blog:
http://www.lettuceeatkale.com
The file:
http://lettuceeatkale.com/wordpress.2010-01-04.xml
The old blog:
http://lettuceeatkale.wordpress.com
Any idea what the problem might be?
