I am trying to put my user name in the text box in the options menu, but everytime I click "ok", or "apply" it says I need to enter a valid email address. So I enter my email address and it says it is too long or contains invalid characters. Kazaa Lite was working on my computer, but since my brother put Kazaa on, and I have since removed it, it wont accept my user name. Whats the deal, and how can I fix this?
