1. Please create/login through Legacy-WoWs [Register] tab.
2. If you do not have a Client, you can find one online quite easily, for your convenience we have provided a link for you below:
3 While that is downloading, download our current Patch-A.MPQ. Once you downloaded the client, open the folder. Once opened, locate the 'Data' folder. Place the Patch-A.MPQ inside.
4. While you are still in the 'Data' folder, locate the enUS folder, open that and finally you will locate the 'Realmlist.wtf' file. Delete the text within this file, replace it with the line below.
set realmlist logon.legacy-wow.co.uk
So as long as you followed the steps correctly, you may now start playing! If you need any help, do not hesitate to create a support ticket in game, join the discord for current updates and the most recent MPQ updates! Cheers!
