I can't enter the username/password anymore

[EduardoReche]

More than a year ago I played notpron and recently decided to come in to play again, but now since the first level that you use Username/Password (level 4) is impossible to enter, i know the **spoiler removed and the answer to solve the riddle but i can't pass the User/Passwd box message, i talked to my friend to try to solve the riddle and he got the same error. Does anyone have this problem too and know how to solve it?

Solve the level again, don't rely on previous answers. Many have changed.
