I am getting database error for snapshot plugin

Greetings,

I am getting the following error for the snapshot plugin:

[09-Dec-2013 12:35:21 UTC] WordPress database error for query SELECT option_value FROM ht_options

WHERE option_name = 'wpmudev_snapshot' made by do_action_ref_array, call_user_func_array, WPMUDEVSnapshot->snapshot_backup_cron_proc, WPMUDEVSnapshot->add_update_config_item, WPMUDEVSnapshot->load_config, m_wpdb->query

Is this a known issue and is there a fix?

thanks
