I have three blogs. The original email address was set to the default, "non-functional" webmail that the webhost provided. I forgot the username and password, and eventually changed (by using phpMyAdmin) the username, password, and email addresses. These new usernames and passwords work when I login at my websites.
However, these don't work when I try to log in at http://www.wordpress.com.
I want to download these sites with software called BookSmart (Blurb.com book-making software), and this requires such a username and password.
What do I do? If I enter a username and do the "lost password" prompt, nothing happens. I don't receive any message. I'm at a total loss. I've been working on this for days without success.
