Ĺadny brzuch
Witam.
Próbuję napisać program który będzie obsługiwał protokół gg, ale stanąłem na punkcie logowania się do sieci. Nie mogę się zalogować. Dane są na 100% poprawnie wpisywane. Opieram się na tym opisie - http://toxygen.net/libgadu/protocol/
Kod wygląda tak

Problem jest taki, że cały czas w odpowiedzi od serwera dostaję 0x0043 czyli błędne logowanie, zamiast 0x0035 czyli logowanie poprawne. Może ktoś pomóc ?:)
