I had posted my first request for help as a new user with upgrsding to 3.7.1 several days prior. No one responded so I continued trying. I came across this site on the Internet and successfully installed 2.7.1 in approx. 20 minutes. I have to add my links from the 2.5.1 installation. I'm unsure what to do about the URL which has been listed with many sites "wordpress" I had to install the 2.71 in "wordpress2"
