That error is so annoying... I just bought Minecraft a while ago


and works perfectly, but when i want to connect my Xbox Live Account it just dont connect, it says "Something got wrong, try again in our site" or something like that...





And when i finally connect, i try to play on some servers or with my friends, it says to set up my acc.



Please help me with that bc i just spent 20 reais on Minecraft and i want to be worth it!
