Fatal error: Unknown: Failed opening required 'auth.php3' (include_path='C:\Parallels

[Nacho999]

Hi,
Can anyone help please?

I have Plesk Small Business Panel version 10.2.0 on a Windows VPS Server with 1and1.

I had attempted to update plesk to 10.4.4 via the built in plesk updater. It failed during the upgrade and now when I run my plesk control panel I receive the following error:


Warning: Unknown: failed to open stream: No such file or directory in Unknown on line 0

Fatal error: Unknown: Failed opening required 'auth.php3' (include_path='C:\Parallels\Plesk\admin\plib') in Unknown on line 0

I've spent an age trying to find out what is wrong, it doesn't appear in my Add / Remove programs so I can't attempt a repair.

Should auth.php3 appear in C:\Parallels\Plesk\admin\plib ? Because there isnt one there.

Thanks
