Try to login it again then when you get it wrong it will say something like forgot password? Click it then type in your email and then type in the words they gave you then click send. Then after you sended it go to your email check your mail and look untill you see the account you was looking for. Then read what it says to reset the password and the new password will be emailed to you, then type in the username, and it's better to copy and paste the password to paste it in where it says password, and thats really about it. If you was to change it go to your pm's and then go to email and password then change it.
