This error can occur when the base-level TSM BA client is upgraded to a newer version. In certain situations, the TSM API runtime files get out of sync. This issue was solved by (un)installing all the TSM components in this order:
1. Uninstall Data Protection for SQL.
2. Uninstall the base-level TSM BA client.
3. Reinstall the base-level TSM BA client.
4. Reinstall Data Protection for SQL.
