Activity Feeds issue with Lead form

Whenever I try adding the Record Wall to the Lead form, I get the following error:

Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: role With Id = 167bcba7-0b38-e211-ac50-00155d0a3009 Does Not ExistDetail:

At one point in time, I had two lead forms, but after reading this article, I removed the second form to try to fix the problem mentioned above.  No joy.  Any assistance would be great.

Thanks,
