Using Support-New Version Check determined Version 21 is available, and download Norton Download Manager, run it to get the new version. Did that. The download begins, but when it reaches 100% is simply starts over. By the time I got to it, it had downloaded about 3 GIGABYTES out of my plan's 15/month, and was starting yet again. There was never an installation file to run. I killed it & stopped the download. OK, what do I do to get the update to ver. 21?
