When you enter TamaTown make sure you enter your username correctly (and if capitals if necessarily). If it is under 5 letters, don't forget to write in the spaces - I am sure that is whats wrong.
Eg. If your username is GREY_ (_ stands for space), when you enter a username you must type GREY and space, not GREY and that's it.
After doing that - with your own user of course - , try the passport password again - it should work.
