Thank you for the information.

Are you running a modern version of Firefox? I just tested in the latest version and it is working fine on Windows.

IE8 is no longer supported, I suggest an upgrade to IE9 and see how it goes. I will add a note for the development team that they should detect old browsers and give a specific error message.

Let us know if a newer browser works. If not I can provide you with a link to the old login.
