Well many people doesen't know about such things as Player Control Panel. So I did a little research on this repack and found out how to get unstucked without the control panel. XD
1: After you get the message you will cry.
2: Write fixme as password.
3: It should say "Blabla already logged in".
4: You will probably type fixme again but wrong password, write your real one.
5: Type your PIN and logon!!
