PW not working? / Confusion

My PW suddenly stopped working. The PW that is in my Keychain will not allow me to log into to apple.com/ YET - Here I am. I don't get it. And I can see my apple mail. But if I type apple.com, or tv.apple.com (to see apple tv) it asks me to enter my PW, and when I do, the box just shakes. Am I logged in to apple or not?

And when that box shakes, there is no option given to reset PW. I'm not sure this will ever post, since whenever I click on Continue it is just grey and nothing happens.
