Hi Trying to upgrade to the latest version but fails and error logs show

Unknown Error: AbanteCart core v.1.4.1 SQL-ERROR: "array (
'error_text' => 'Table \'db769632144.abc_customer_sessions\' doesn\'t exist',
'errno' => 1146,
)" in /homepages/10/d4527924**/htdocs/mgbregalia/core/lib/package_manager.php on line 832

Any Ideas?

Thanks
