If have not then that is good.
There will be a option below forgot password? Click that n you will get notified to change your password.
N if you forgot both then send a mail to the official board and get in contact to them. They will help you out.
Don't do this again. Store it some where. This will cost you much. Those are important for you.
Hope this helps!
As you said there is some problem while getting registered then better to contact to the board by putting a mail or make a phone call.
Better you hurry. Else it might be something important you may lose.
Hustle!
