It's entirely possible that the Adobe server may indeed be down when you try.

Found the problem. After a couple of very frustrating hours, and trying everything I could possibly think of with firewall and internet settings, I decided to just just try plugging in to my modem directly instead of working over WiFi. Adobe Updates from within the program ran perfectly, first time. The issue, as bizarre and crazy as it seems, is that you can't run updates when you're working on WiFi. To prove it, after my updates were downloaded and installed, I tried to run the updater again and received the same error message. So my problem is solved. No WiFi when trying to run updates!!!
Interesting. Thank you for reporting back, btaylor5.
