Locked Out

Yahoo won't let me into my yesterdaylooksgood e-mail account. I can log into my other one just fine. I've had this happen now and again, but it has never lasted 12 hours! It is driving me nuts (of course) because I know from Messenger that I have two new e-mails in there. Anyway, if one of those e-mails was from you, you'd better call, I guess.
