Can't log in to my minecraft account

[NappaKappa]

Basically, this is the first time in what must be two years that I'm playing technic. In the meantime, I've migrated mojang account and have changed my username and password. Your system seems to believe that my credentials are invalid. I've tried all combonations of username and password I've ever had and it still believes they're incorrect. If you guys have some sort of solution I'd very much appreciate it as soon as possible

if you migrated your account to a Mojang one then your email that was confirmed by Mojang is the only acceptable username
