Importing WXR

I’m moving my domain to a new hosting company. In the process, I’m changing my blog from http://www.thelifeofbrian.info/blog to blog.thelifeofbrian.info. I attempated a database export/import and that royally screwed things up, so now I’ve done a WXR export/import. This seems to have worked, except that I’m missing posts from June 18 to yesterday. I opened the WXR file and can see that the posts are there. Help! How can I get the remaining posts imported?
