Birthday email issue

[marinelife]

When I run Scheduled Task Manager
birthday

It says done but has the following error and no email is sent
Fatal error: Class 'vB_QueueMail' not found in /home/****/public_html/saltgeeks.com/club/core/includes/functions.php on line 828

Thoughts?

If you run Maintenance > Diagnostics > Suspect File Versions, are any files missing or showing unexpected contents?

LoggerConfigurationAdapterXML.php

File does not contain expected contents
