Show related content on a Case Visualforce page

I have a VF page where I'm looking to display related content on it. From the documentation I found (https://www.salesforce.com/developer/docs/api/Content/sforce_api_objects_contentdocumentlink.htm), you need to query the ContentDocumentLink object. Here's what my code looks like:

String eyeDee = Apexpages.currentPage().getParameters().get('Id');
thisCase = [SELECT Id, IsClosed, Subject FROM Case WHERE Id =: eyeDee LIMIT 1];
for(ContentDocumentLink c: [SELECT ContentDocumentId FROM ContentDocumentLink WHERE LinkedEntityId =: thisCase.Id])
            kIds.add(c.ContentDocumentId);
content = [SELECT Id, Title, Description, Owner.Name, CreatedDate FROM ContentVersion WHERE PublishStatus = 'P' AND IsLatest = true AND ContentDocumentId IN: kIds ORDER By CreatedDate];

When I load the page however, I don't get any results. 

On the standard page (https://www.dropbox.com/s/fov495yzhyelami/Screenshot%202015-01-19%2012.46.15.png?dl=0) I can see the content. On the VF page, I don't get anything.

VF Code:
<apex:pageBlock title="Related Content">
   <apex:pageBlockTable value="{!Content}" var="c" rendered="{!Content.size != 0}">
      <apex:column >
          <apex:facet name="header">
               Title
          </apex:facet>
          <apex:outputLink value="/customers/{!c.Id}" target="_blank">{!c.Title}</apex:outputLink>
      </apex:column>
      <apex:column value="{!c.Description}"/>
      <apex:column value="{!c.Owner.Name}"/>
      <apex:column value="{!c.CreatedDate}"/>
   </apex:pageBlockTable>
   <apex:outputText value="No Content Related" rendered="{!Content.size == 0}"/>
</apex:pageBlock>

Any help would be awesome.

Hey, Christian, I think for the Related Content list on the Case object, you want to query ContentDistribution instead of ContentDocumentLink. Would you give the following query a try instead?

  
SELECT ContentDocumentId, ContentVersionId
FROM ContentDistribution
WHERE RelatedRecordId =: thisCase.Id

@Marty, tried that. Getting this error: sObject type 'ContentDistribution' is not supported.

Can you try changing the API version of your Apex class to 32.0 (Winter '15)?

@Marty, that did it. Thanks so much for your help.
