My Facebook Timeline is telling me that my e-mail is not an account?

[Brandy Todd]

Hello! Some help would be greatly appreciated.
I have had facebook for a few years now and log-in normally all the time. Well recently facebook timeline prompted me to update my e-mail address, since the one I created the account with is no longer one I use(very old). I finally did so, gave them my updated e-mail address, and it sent a confirmation to my e-mail so I could now use it from the updated e-mail. I logged in a couple times and it worked fine! I even went to my profile and made sure my new e-mail was hidden from my page as well as the silly one they gave us all.
*But now the question..I try to log-in this morning and this is what its telling me 'The email you entered does not belong to any account.'
Okay so not understanding, I even have the chrome where it automatically types your e-mail correctly so I know that's not the issue. I know facebook will never get around to helping me, but I need some smart people out there who have good answers!

I do need it working, I don't just use facebook for fun, there are certain people I keep in contact with our non-profit organization so I'd like to have my facebook back ! Thanks for reading sorry if its lengthy but please any help??
*Something I just tried because I happened to remember it, I put in my 'e-mail' that facebook gave me (they gave everyone one), and when I did that it did log me in.But it still won't work with my regular e-mail.

Have no clue what's up but I'm hoping they aren't switching all of our log-in's to the e-mail they gave us! I barely remembered mine, I doubt other people would.

Hopefully its just a glitch this morning, guess we'll see. Helps to know though its not just me..*
