It is very strange. I have never heard about anything similar in any other game. Moreover, Eve Online is the best on the market and this kind of things should not happen to it. You must be sure that you have filled all the required fields. Sometimes that is the reason that someone cannot register. If that is not the case, several more things can influence your registration. Maybe the server load is too big and it needs more time to process your registration. If that is the case, you must be patient. In either case, you are going to be very happy with the game when you create account and start to play.
