Standard Reports empty

I share your pain here. I had the same thing happen on my K2 dev box when i first started using it. this was given to me from a K2 guy

If you are encountering issues with the Reporting Services component, validate that the following configuration changes were made to the appropriate files, located in the below folder:

C:Program FilesMicrosoft SQL ServerMSSQL.1Reporting ServicesReportServer

Note: In the location above, note that the MSSQL.1 directory depends on your specific environment. Your folder may differ depending on where Reporting Services was installed.

rsreportserver.config file:

<Configuration>

   <Extensions> 

      <Data>

         <Extension Name="SOURCECODE" Type="SourceCode.Data.SmartObjectsClient.SOConnection,

SourceCode.Data.SmartObjectsClient, Version=4.0.0.0,Culture=neutral, PublicKeyToken=16a2c5aaaa1b130d"/>

      </Data>

   </Extensions>

</Configuration 

rssrvpolicy.config file:

<CodeGroup class="UnionCodeGroup" version=" Name="CustomDataExtensionCodeGroup" Description= "Code group for the Custom Data Extension" PermissionSetName="FullTrust">  <IMembershipCondition class="UrlMembershipCondition" version="1" Url="C:Program FilesMicrosoft SQL ServerMSSQL.1 ReportingServicesReportServerinSourceCode.Data.SmartObjectsClient.dll"/>

</CodeGroup> 

Hi Ruud

Are there any errors or is the report just empty? Browse to the Reports web site and ensure the Workspace Service account is a Content Manager. Also try running the report directly from the site, the reports can be found under Standard Reports > Hidden. Does it work from here?
