I just installed MWG 7.2 .0 build 13043 on VMware workstation 7 for test, but when I added DLP ruleset I acn't access any URL, and have the attached error page.
I only have the attached errors that related to updater, I have informational alerts for DLP filter updates, no dlp engine update.
It looks like that updates aren't working on your machine at all. Please check, can you machine get access to mwg-update.mcafee.com
P.S. DLP Filter is built on the top of updatable DLP Engine
I have the following lines in the update file that belong to DLP updates,
