There's at least 3 of us whose login fails. I have the identical problem. I got through to tech support Saturday. The tech could log in to his own account but when he tried to login with mine, it failed. He gave me a replacement password to use with my email address which also failed. He said that he was turning into their troubleshooters but he thought it probably was from the work they are doing on the new sync ability. I'm supposed to hear from them today, but nothing so far.
