[Technic Launcher "Incorrect username field/password field combination]

Can anyone help me , ofcourse i have a mindcraft account , now i want to play tekkit , so i download the TechnicLauncher.exe (I have an windows xp computer).

then i start it and it is asking me for username and password(in the youtube tut. i see people don't have to do that ).
