The issue with the SMS 2003 Asset Intelligence catalog update has been resolved and a new package posted to the download site. So, if your site database was hosted on a SQL 2000 instance and you received syntax, constraint creation, or other errors previously during the bulk import you should get the new catalog update!

The Asset Intelligence forum has also been updated to reflect the new refresh as well as root cause:
