I Changed my name last night. My ign was Hornet19_2K14. Than I changed it to Hornet19_2k14. Ever since I tried to change my name, I try to join a seRver and it says "Not authenticated with Minecraft.net" and, I basically can't play minecraft? Anyone know how to fix this? I need help please?
Which server? Did you try with more than one server? It might be on the other end. I had a similar problem and removing the account on the launcher and re-adding it fixed it.
I Am in need of help! Please.
