So I played for like 4 hours this morning and then I exited the game, when I tried to open it again to night I gott an error that said: Data/enGB/wow-update-enGB-18273.MPQ: World of Warcraft can’t make a required change to an archive file. Be sure you have write permission for the World of Warcraft folder or try running the game in administrator mode. For more information, see: https://battle.net/support/article/6910
Firstly, move your WoW folder away from the download folder.
Right-click on the game folder (the folder containing WoW.exe and the rest of the game files). Then, click "Properties", and un-check "Read-Only". Make sure "Run as Administrator" is also selected. Finally, click "Apply", and then "Ok".
Try launching WoW.exe now. Let us know if that doesn't work!

Prueba esto:
En primer lugar, mueva su carpeta WoW fuera de la carpeta de descarga.
Haz clic derecho en la carpeta del juego (la carpeta que contiene WoW.exe y el resto de los archivos del juego). Luego, haga clic en "Propiedades" y desmarque "Sólo lectura". Asegúrese de que "Ejecutar como administrador" también esté seleccionado. Finalmente, haga clic en "Aplicar", y luego en "Aceptar".
Intente lanzar WoW.exe ahora. Háganos saber si eso no funciona!
