CAUSE

Cause 1

This problem occurs because the custom data processing extension that Microsoft Dynamics CRM 4.0 uses is registered incorrectly on the SSRS server. This behavior may occur if the Microsoft Dynamics CRM Data Connector for SSRS has been uninstalled or if the Microsoft Dynamics CRM Data Connector for SSRS is configured incorrectly.

If you install the following Critical Update for SQL Server 2005 Service Pack 2, the Microsoft Dynamics CRM Data Connector for SSRS will be removed:
