I did a manual deletion of the two directories and am happy to announce that the CB1.2.1 is now installed. Thank you very much for the help.
I do have a couple of problems still, however. First, the directions said to put an entry in the Users Menu and I don't seem to have a Users Menu. I put the items in the Main Menu instead for now, but where is my user menu?
Second, and more important, when I tried to install the MyCommunity Template I got an error that said that the version I was using was older and I would have to use the Legacy plug in. This happened the first time and I used the Legacy plug in, but I don't think I should have to do that. I am sure I used the 1.5 template, not the 1.0 template, but I did notice that both templates have the same date, time and size so I am wondering if they are both 1.0?
Lastly, I did notice what I believe is an error in the README-NEW-INSTALL.TXT file on page 9. At the very top it is telling you how to turn the user registration off and says "Configuration->SITE(Joomla ...... It should be SYSTEM, not SITE.
