Hi, Did you executed the Sql scripts after the update? follow this link to verify that you completed every step after CU4 update. http://blogs.technet.com/b/kevinholman/archive/2011/02/01/opsmgr-2007-r2-cu4-rollup-hotfix-ships-and-my-experience-installing-it.aspx - Run the SQL script(s) update against the OpsDB AND Warehouse DB. Time to run the SQL scripts.
