CactusCraze

I can log in on non modded and any other modpack louncher just not this one. I use my email and password to login becouse it won't let me use my username. So I checked the mojang website and it says I don't even own minecraft besides the pocket edition (whitch I do).

It says I don't own minecraft when I do I can use ftb and know I do not own a cracked version PLEASE HELP!
