no, maybe its just you or few more players, send support ticket instead, and post this in technical support area

Sometimes I try to log into the game and I get a "Set up an account in www.navifield.com" message. If I log into the website and try again in the game, I can log in normally.

I have no idea if the two events are even related, but it's been working for me.

have you verified your account?
