Why is facebook not letting me sign in?

[This is it.]

I was online this morning. When I try to sign in, it says "Incorrect Email/Password Combination."

When I click "Forgot your password?" and enter my email, it says "The email address you entered has not been registered."

I am CERTAINLY registered. I'm spelling everything correctly!
I have tried deleting cookies, nothing is working. I've messaged the facebook staff, but I doubt they will be speedy. Is it possible for them to LOSE my information? Is anybody else having this problem?
Its definately the real website.
I just got my friend to look on facebook, my accounts still there.

And I gave her my info over the phone (I trust her), and its doing the same thing for my account on her computer.
