Any luck? If they won't let you reopen the wiki, you might still be able to get a database dump. For recently closed wikis, just go to the wiki and you will be greeted with a "wiki closed" page that has links to download the database. If that doesn't work, you can try accessing the file URLs directly; but you will need to know what the wiki URL was.
