How to make the mods work?

Well I tried putting the editted kom (data037.kom) to the data folder then opened up elsword uk and wait for it to patch then logged in and did a dung but it didn't work. oh and im talking about the Mob mod by xxxxx1995.
Thanks in advance

Put the editted kom after elsword is patched, try to put in the elsword folder before th e hackshield is loading done

I still don't get it.. so put the editted kom after the Elsword patch thing is done? like the one that says "Checking Version" everytime you start it up? and also... what do you me try to put in the elsword folder before the hackshield is done loading?

step 1 : run the elsword
step 2 : wait till hackshield/gameguard logo appear
step 3 : copy the data037.kom to folder data (P/S : you should back up your original data037.kom)

its should works

Oh I see, does this work for UK version? and also, if i want to stop modding, then can I put the backed up original data037.kom back to the folder or do I have to wait until the hackshield logo appear and put it back?
