Upgrade from 11.5 to 12.018 error

[C1oudM]

Hi
i a use a Webfusion VPS
stupidly i upgraded from 11.5 to 12.018 without first backing up the server - school boy error!

the update stated all was well, and all websites, ftp, Virtuozzo access etc.. all works fine except i cannot login to The Plesk control panel

it states:
ERROR: Exception
Function not implemented

webfusion sent me details of the error
Exception: Function not implemented file: /opt/psa/admin/plib/Lock/Manager/Hierarchical.php line: 105

the php file in question simply has random characters displayed and there isn't a line 105:

this is the php contents:
<?php
die("The file {$_SERVER['SCRIPT_FILENAME']} is part of Plesk distribution. It cannot be run outside of Plesk environment.\n");
__sw_loader_pragma__('PLESK12');
?>

either the above is some code i am not aware of or this is simply a corrupt file
if so does anyone know the correct php code that should be in here?

thanks
