Not Authenticated with Minecraft.net?

Locked - don't necro post.
Some advice on how to fix this was stated at the start of the thread, if that doesn't work try contacting mojang support.

hi guys -snip- and i tried everything but it still dont work help

I'm having the same problem. MineaFairy to War Pixie. . .whatever

I did that but it STILL Cant work how????

I am having the same exact things Its not working how do i change that

lol if u log out and log in again it actually works thx who ever wrote that

the same thing was happening to me so what you have to do is open up your mine craft launcher and it should say in the bottom right corner welcome (your name) ready to play mine craft under that should be a button that says switch user click that then sign in to your mine minecraft account

Which happened to me.

Before changing your name, contact your server administrators and be 100% certain that they are ready to handle name changes. They may not be, and you will be stuck for at least a month with that new name.

anyone else lost their ranks on servers?

i found solution, on your launcher you gotta logout then logout your "username or whatever profile name" then relogin then it should be pops up your new username profile instead of your old username profile ( it happened to me too but relogin fixed it after i changed my username)

It probably is, as everything is online; http://xpaw.ru/mcstatus/
Try again sometime later, perhaps google a bit, you'll probably find something about it, if nothing works, try changing it back (if possible)

same problem
