Every time i try to join Dalek Mod Universe Server Public i cannot .

Failed to connect to the server 

Failed to login : Acess token can not be null or empty

HELP!!!!!

Try restarting your game and see. Your connection to the server could also be affected by your internet connection.

 i tryed it , not works

i can join every other server without problem , idk what is happening

heeeeelp

 Have you logged in with your SWDTeam account through the button the title screen?

yep!

Goto your Account Settings and add your Minecraft username.

erm .. i tryied it , but allways say : username does not exist . 

Are you sure you typed it correctly? Same for your password. 

What is your Minecraft username?

I'll try adding it manually for you

 Thx 1WTC !! my MCusername is Whovian98Alef

 pretty sure!

 I've looked up your Minecraft username and it doesn't seem to exist.

Open the Minecraft Launcher and tell me what name it says on the bottom right:

 yes , is this , but , maybe its why , my minecraft isn't original??

Are you on a premium account?

Or are you playing a cracked version?
