@Dalcom there should be a file called inject.dll in your game folder after you patch and start the game. if not, check your anti-virus software and make sure yiur disk is avaliable to write. You can also copy the inject.bin and rename it to inject.dll manually to the game folder.
Please use English here because I don't understand Korean. Or you can contact your localized mod creator.

방법대로 설치했는데 한글패치 불러오기 실패 창 뜨고 내용으로 inject.dll 을 불러올 수 없습니다. 라고 뜨는데 어떻게 해야할까요?
