I was using new launcher without any problems. and today when i saw that release of 1.6.1 appeared in the list i was prety happy that it's finally released. so i tryed to login but it's does nothing and after a while it's gives me error that my username or password is wrong, I was like wtf? so i tryed to login with old launcher and to minecraft.net and it was ok. so what is a problem? :/
