Missing DB Column

When trying to add a new text field the following error is produced.

User warning: Unknown column 'locked' in 'field list' query: INSERT INTO content_node_field (field_name, type, global_settings, required, multiple, db_storage, module, db_columns, active, locked) VALUES ('field_companywebsite', 'text',

(The rest of the error screws this page up really bad.)

I am not using Views and am using Drupal version 6.4

I checked my database and there actually is no column named "locked".
