I am running SBS 2008.  When I connect to the database through SQL Express and try and open a table I get the following error : blocked because the signature is not valid. I can deighn a table no problem.  

In the event logs : EVENTID: 6398 The Execute method of job definition Microsoft.SharePoint.Search.Administration.SPSearchJobDefinition (ID 51e6fb53-ed1d-42b8-ad9c-44c9fda18619) threw an exception. More information is included below.

Access to module dbo.proc_MSS_Cleanup is blocked because the signature is not valid.

Can anyone help ???

    I assume this is a SharePoint services issue. There's an attesting dll
    which is codesigned with a certificate. I assume either this dll is missing
    or the certificate has expired. The other possibility is that the software
    has changed without a corresponding change to the table signatures. This
    would most likely be an upgrade issue.
