2 problems:
1. it's not necessary but why the player's password look like digits in the user file [Password = 104268307]

2. when an unregistered player join the server and click on "Quit" instead of entering a password and click on "Register", the server will kick him and the account will be save in users file even he didn't press on "Register"
So the problem is when he join the server another time, the server will ask him to login using a password. and he didn't enter a password on last time, he did "Quit" ..
