Update Plesk = 404?

[gasxtreme]

Hi,

I saw a link in plesk to update plesk, and it reads:

Information: New updates are available for Plesk 8.1.1, Plesk 8.2.0

The problem is however that when I click on the link to update, I get the following 404 error:

Not Found
The requested URL /server/autoinstaller_releases.php was not found on this server.

How do I go about fixing this?

Thank You.
