importing wordpress.org xml file

I had some trouble setting up my hosting to have 2 domains and wp on each. I had to uninstall and re-do. I downloaded an xml file of the website i had already created. Well, when I imported it after setting things up correctly, the information is there, but all of the hard work – theme selection, widgets, etx – aren’t.

Did I do something wrong? I used the wordpress importer.
