I am trying to install Ubuntu on my notebook using the CD that was sent to me. I am stuck at the "Who are you?" Intallation screen. I have all my information inputed but I can not get passed this screen. It will not let me forward. It is waiting for my reaction but I cannot get passed this screen.

Your username can be made only of lower case characters and numbers.
And Ubiquity unfortunately provides any error message.

Please mark question as "Solved" (after having succeeded, obviously).
