Export not working :( WP.com to WP.org

Hello there. My question’s fairly simple, but with the GREAT luck I have, it seems things never work out the way they’re supposed to -_-” I’m trying to export my blog (http://www.clicheanime.wordpress.com) to a WordPress.org site on a free web hosting service: Freehostia. My new URL will be http://finallyanime.freehostia.com

My problem is the following: I made the export file like I’m supposed to from my WP.com site. It’s in XML & I use the import function in WP.org, but it just goes to an empty screen when I finish uploading…and there are no new posts…tags…categories…comments…nothing. Can someone please help me? And I checked the file size, it’s only about 839 kilobites I believe. Definitely not 2 megs.
