XMLResourceRenderer error after install CRM-Business Package

Hi together,

I've installed the Business Package Business Package for SAP CRM 4.0 60.2.3 (BPCRM40602_3-10002661.ZIP). Now I have a error at the first page where the new are displayed: "Resource cannot be displayed with XMLResourceRenderer" for every news which I have.

Have anybody a idea what is the reason for this error and how I can solve it?

Regards Thomas
