New Blog Templates not copying files or setting page/post ownerships correctly

I'm using New Blog Templates in conjunction with Pro Sites. It works great - except for two issues:

- the pages and posts from the template are copied into the new site OK, however the ownership of these remains the owner of the original template blog. Ie - the 'post_author' and 'guid' fields in the wp_X_posts table are not being updated to the user id of the newly created blog.

- files/media are not being copied into the new blog, although I do have that box checked in the settings for the plugin.
