Well well WELL! I tried the links with no luck. One of their suggestions was the one Feuer Frei! said might help, except they had a space before and after the '/'. It didn't work. When I got to Feuer Frei!'s post I recognized the difference.
Well, I have now installed the newest version of Installer, the Adobe Reader update finally worked and I've just finished updating MSE. That did the trick.
Thanks all!
Now to see if I can reinstall AVG.
