I actually have a similar problem, but not exactly... lol

I have recently reformatted my iPad and I didn't transfer my game. Though, I do have a name and pass, I type it in - nothing pops up. Figures. It would be nice if Kingdom Age had a set user name and password so we don't have to worry about these types of situations.

It sucks, because I really enjoy the game. But, I guess you have to send a request in with your UDID, game character name/number etc. I still have yet! to receive a reply. Which makes me want to suggest something else - A LIVE SUPPORT on their "support" web page.
