I can't log in since I accepted the new download today, 1 Dec. 2016. I click on the icon, and see the notice that Second Life is loading. I get no farther. What is the problem?

It's hard to say, but the viewer may have been damaged during the download or installation.  It's not unusual, especially if your Internet connection is a little wonky so it hiccups during the download.  You'll need to download a fresh copy and try again.  Before you do, though, reboot both your router and your modem to let them get a clean grasp on an IP address.  Just unplug them both from the power for a few minutes and then restart everything.  Incidentally, avoid using a wifi connection.  Linden Lab neither supports nor recommends wifi because of the possibility of data corruption and signal loss. Use a direct cable or DSL connection instead.

Once you have done that cleanup, do a Clean Install to get the upgraded viewer in your machine.  Here's how >>> https://community.secondlife.com/t5/English-Knowledge-Base/How-to-uninstall-and-reinstall-Second-Life/ta-p/1375231
