Installed Aion, launcher was english but once got to log in screen everything was korean. :/
I tried to change language setups in launcher's properties/settings but didn't help at all..

People keep telling about 2_enu.pak and renaming Aion folder to AionEU

Which one of these will work?

Renamed folder to AionEU and whole patch updating fucked up "Can't load patch xxxxxx" reinstall whole game :S

How come this is so retarded..

1) Launch NCSoft launcher
2) There should be Aion under Installed tab and another Aion version under the Not Installed tab.
3) Right click the Not Installed version, choose properties and paste your Aion installations directory.
4) You will get a prompt to overwrite. Do it.
5) Change NCSoft launcher settings to your region.
6) Update Aion
7) It should start downloading an ENG language patch and NOT EU_ENG one.

this worked for me

had same problem

Okay gotta try it once done patching

Now working, had to copy 2_enu.pak to Aion..
