To be exact it says when trying to go to the firewall settings:
The faulty DAT update (6807) is reported to be producing script errors in Security Center.
Try forcing a manual update from Security Center or the McAfee icon in the System Tray and see if the errors persist. If you get the latest DAT (said to be 6812, although I'm on 6809) and you still get script errors, you may need to uninstall, run MCPR, and re-install.
I tried doing the following, but each one I try give me the same error(s):
Unable to find any qualifying McAfee products.
Could not find language file in disc image.
Try to run McAfee Virtual Technician (MVT) this is an automated self-healing tool that can diagnose and fix many problems related to your McAfee product.
You can download and run McAfee Virtual Technician (MVT) from mvt.mcafee.com
