Unable to upgrade Plesk 9.2

[Micron21-David]

Hi,

When attempting to upgrade my Plesk 9.2 for Windows server (running W2k8), I get the following message;

Error: Unable to retrieve a list of available updates: Unable to run `pleskautoupdate` utility: System.Exception: The remote server returned an error: (404) Not Found. http://autoinstall.plesk.com/420FF3A6-FF3D-4B04-A9F2-896B2692EFB7.xml.crc
at PleskUpdater.Updater.check()
at PleskAutoUpdate.App.Main(String[] args)

This happens both when I try and uprade from the web interface or from the updater utility when remotely logged in to the machine.

Any ideas how I can resolve this issue and move on to version 9.5?

Best Regards,
David
