Last night I attempted to install this mod on my vBulletin 3.7 forum:

The installation seemingly did nothing so I uninstalled it through the Product Manager. Unfortunately following this I've received nothing but mySQL errors ever since.
Here are some of the "1054" errors (there are additional ones referring to various unknown columns):

I would just restore my board to the latest backed-up version, but the same day this happened my host suffered major corruption on their backup storage unit and, as I write this, they think a database restoration is not possible.
I've attempted reimporting vbulletin-language.xml, reuploaded all the original vB non-image files, removed any other .xml files from the includes directory, disabled the plugin system in config.php, ran upgrade.php again, repaired all tables in phpmyadmin... no luck with anything. It should be noted that I cannot access the admin CP or any page on my forums.
I'm trying to repair a forum with 1.8 million posts and seven years of data, so any help would be tremendously appreciated. Thanks.
