I followed the instructions you provided, including turning off the Real-time scanning and Firewall in the McAfee Security Center, with no success. Performed the action twice with the same result--Connecting to Server, Downloading: V2014.03.22.08, followed by the error '6' and overflow message. As I mentioned previously, I had been running this version for sometime, including updating the database, with no problem until I attempted to update the database several days ago. At that time the message was, "the database was out of date by 7 days (approximately), would I like to update."
