Upon going to CO.com I get an account update screen (PIN Hint, username, password, etc.)

I entered the same username I had picked a while back, and I get an error that someone has already picked that username. Well, duh! That user is I.

I click on My Account (where my username had disappeared from My Account) and it lets me enter the same username.

The screen that sets my password does not work when you hit Enter (just like the login screen). You have to click on the button. If you hit Enter you just come back to the same page with no error. Very annoying.
