Just noticed your log in at the top of the page looks different. As an FYI, the log in does not function properly with Firefox browser. I kept trying and it didn’t work. Log in was fine using Internet Explorer.
I’m sorry you’re running into trouble. Which version of Firefox are you using? Are you on Windows or Mac?
