You should be able to repair it through something like phpMyAdmin (or tools.php from the do_not_upload folder of vBulletin download - though I'm not 100% sure).

If you other admin can still login or has access the Maintenance section of AdminCP then you can use that to repair it. (AdminCP > Maintenance > Repair/Optimize Tables)
