Doesn't work, Give alot of error on wow.exe 32/64 " The CAS System unable to initialize" "Client Handler cant initialize".

Im a newbie here, butt a i have 2 Questions:

1- We need the full game version for play that?



2- If you dont have the game, how can download the contant if alocate ip is own machine. Is impossible to download contant.

ps:Step 7:After you are done with it & if you don't have Client (7.0.3.22423) then you will go to mmoprorepack "Client(GAME)" folder and will start wow.exe or wow-64.exe depending on your OS - It will take sometime to start (depends on your internet speed because it require to download some files before starting wow legion
