First reinstall EUKO
After reinstall KO down those 2 zip files
open both of the zip and extract all the files inside the zip to your EUKO folder. Remember to overwrite everything.
Open Server.ini in your EUKO folder and change
After that just launch the launcher it will update automatically, for those who stuck while updating hackshield, just wait.. It might be your connection is slow and it will take sometime to finish all the HS patches. (mine took around 5mins :S)
