So I logged out to change my name... and I went to go back in and it keeps saying "Failed to join server, Unable to contact Mojang Services" Help??
I'm in the same boat... I got that last night too... never got back in... when I logged in this morning, I logged into YOU HAVE DIED and all my OP stuff was gone. This is the 2nd time this has happen. Thank heaven for too many hours on line and a good stock of OP equipment.
If you have changed your name, you need to create a new account in the minecraft launcher using your email address.
Turns out it was the Mojang services being derpy. I am on right now. And in my new username as well. But I only plan to keep it for 30 days. :3
