Game logs out after trying to join in with character.

Ive been a way a while. Im using the Mist of Pandaria Minimal launcher.

My characters have to be renamed. After I do so I select then and am playing for about 1 second before things logout.

"Data/enGB/wow-update-enGB-17325.MPQ: Cannot stream required archive data. Please check your network connection. For more information, see: https://battle.net/support/article/6250"

Blizzard killed the MoP Streaming server long time ago now, you need to have all the game files before trying to play.

Well that one allows me to login, see my characters, its just crashed when I load the characters and I dont know why,

If I try the full client then it tends to get stuck on endless "Connecting"
