I am using WordPress 3.5.1. I am taking over responsibility for an old blog site. I want to import all the text and posts into a new WordPress site. The old admin people sent me a .xml file. How do I Upload this information into the new blog space? I have gone to Tools > Import > Blogger as directed by an earlier support posting, but I receive the message "We were not able to gain access to your account." I am given a choice to "Clear account information" which sounds ominous. I do not want to clear out any posts O have entered to date. Help greatly appreciated.
