That's how it looks ingame.
1. Download the Zip
2. Go to your TreeofSavior folder (e.g. C:\NEXON\TreeofSavior\release)
3. Put all files from the zip in there and overwrite the config.xml (on your own risk)
4. Open user.xml and search for Language=
5. Change it to "en"
6. Save everyting and start TOS again
Important: The patcher sometimes deletes / changes files so you might need to replace the config.xml or language files again!
