This is due to version mismatch between the AutomationEngine binaries and the database table schema
Upgrade the Database schema to the current version as the binaries.
Install and configure the Utilities from the upgraded version (if not done already).
Ensure none of the CP and WP services running on the server (on all the nodes in case of an HA environment).
Execute the DBload load utility to upload the UC_UPD.TXT file from DB directory. This upgrades the database schema after the successful execution.
Start the Automation Engine services on all the nodes normally.
