Skills appear in Korean and rejected from server.(3) message

[gpedro153]

So,
 
i downloaded the data archives from the "Recommended Client & Setup" page here at rAthena forum (https://rathena.org/board/topic/70962-recommended-client-setup/).
 
I also downloaded the 2012-04-10 DIFFED client and it works on my server. However all the skill's descriptions in game are in Korean!
 

here is a screenshot:

 

How can i make it appear in English?

 

 

 

Also,

 

i downloaded the 2012-04-10 UNDIFFED + Changes from that same page to create my own client using Shin's Diff Patcher with WeeDiffGen plugin. But even if i diff it by checking the exactly same boxes recommended by the page where i downloaded the 2012-04-10 client, when i choose my character in game i receive the message "rejected from server.(3)"

and then if i press "ok" the game window closes.

but if i use the same client i downloaded already diffed it works fine and i can play... and the skills are in Korean

 

here are the boxes i checked on Diff Patcher
