"Except for a small number of users I have already dealt with directly about this issue -

If you have downloaded VaultWiki 2.2.0 before 10:00 AM (GMT -5 / EST) on February 2, 2009, you MUST download the ZIP again. There was an issue where an old version of special_class_wiki.php was included. If your vBulletin CSS is not contained in an external file, this can prevent you and your users from being able to log in.

We apologize for what could be severe inconvenience. As always, we appreciate your support of the product."
