Post management solution sp2 upgrade issues

I used the SIM to upgrade 2011 Management Solutions SP1 to SP2. However, it shows the SIM as being installed but not configured properly. The Altiris Event Log Viewer is full of errors such as:

Description: Unable to generate policy XML for item: Server (de2fe9d8-a355-42ef-a709-02a37ce52610)

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].
