If you are having a hard time logging in, just go to your tools section on your task bar. Click on delete browser history. Click delete. When it is done, you should be able to log in now. So what happened? The browser history saved the look of the old site and all its pages, etc. including the log in. The new site does not recognize it. So deleting it gets you to a new log in page and now you are able to log in from then on easily like before.
