You need to setup root access so that you can edit your hosts file. From MT Account Center > Domains > (your domain) > Root Access & Developer Tools.

Enable root access. I don’t know what that screen looks like anymore since it’s enabled in my dv already. I don’t know what operating system you’ll be using but then you have to have a telnet client for SSH access. I’m on windows and use puTTY.

Login as ‘root’ and edit the hosts file according to the thread above. Worked for me.
