Maybe nobody else had this problem, but apparently if you chose to open a G Mail account when Blogger changed it's preferences back in July ? and Blogger asked you to open a G Mail account ( I don't think it was stated as mandatory ) it's not then the email address you put in the box on the sign in page.
I think I am finding this to be true consistently, but I'll have to do it more than once to be sure. The ID I originally used to sign is still the sign-in ID in the ID box.
the password is now the password to the G Mail account.
So, am I crazy ? Am I alone in this difficulty ?
I used my original sign-in ID and password. Bogger then added @ juno.com ( I didn't do that ) and then rejected my original password, but instead of saying the password was wrong they said the email addy didn't exist.
I put the G Mail addy in the ID box, and it again said the same thing, no email exists in that name ( both addresses work for me as email addresses )
I erased the ID box, typed in my old ID, typed in my most recent change of password for my G Mail address, and Blogger then let me on. I am sure it's my old brain that has something wrong with it, but if anyone else is having trouble, maybe we can get to the bottom of this. ( in case someone is suffering in silence)
