EM console shows updating error / Error 4081 showing in sophos Em library eventlog

Goodday,

We are using

Sophos Em Library 1.3.2

Sophos Enterprise Console 3.0

We are downloading on a regular base the sophos updates. Since last week the up to date column in Sophos enterprise console shows for every client "Not Since 9/21/2010 ....". I think this is indicating that the clients won't update.

The event log is showing these errors:

I tried several solutions from the sophos site:

http://www.sophos.com/support/knowledgebase/article/40952.html

http://www.sophos.com/support/knowledgebase/article/47152.html

But both didn't solve my problem.

Does anybody has a solution for me?

Regards,

Peter
