Umm sorry but how do you overwrite files?

go to the "www" file, then you go in "data" and replace the necessary files by the english ones :)
obs: if you dont know what you have to replace, delete all the map archieves (minus the mapinfo), the actors archieve, and the system archieve in the korean file, then copy all the archieves in english file and then paste it
