I tried a full PMimport - version 7.1.518
http://support.microsoft.com/kb/982726 - MSWU 431 - this is an old bulletin that gets regular updates. I have trouble with it from time to time, I tried disabling update, deleting existing policy, restaging but still am only getting old version of update. I think Symantec may just be missing latest version released this month in PMImport?
