Launcher not recognizing my MC account

[Xplosion99]

I just got tekkit and a new password for my MC account but its not allowing me to log in. I typed it in several times and it still won't work. Any help?

but it works for logging into vanilla MC?

If you updated your account to a mojang one you'll have to use the e-mail address
