MartyDLT,
You can download the latest version of the PACU via either LiveUpdate or manually from this link (http://www.symantec.com/security_response/securityupdates/list.jsp?fid=ccs&pvid=pac). When you update the PACU (Patch Assessment Content Update), it should also update the Patch Assessment Standards for the different platforms. Go to the link above and look at the Release notes for one of the PACU and you will see what I mean.
Optionally, you can download the PACU and extract it to a folder. Then search for the exported standards' XML files. Problem with this is that if the checks are referencing a new field or has other dependency, this will may not work.
