I keep getting a username and password problem when setting up my yahoo e-mail. I have typed it in a dozen times... I can't be wrong every time. I retyped it in on my desktop and get into the account. What the heck is going on here? Any ideas? I have read the instructions on several sites, watched the video on you tube. Typically a Username/password is a pilot error problem, but I don't know what I am doing wrong.
