It was on another post but just trying to make it public for those that did not see it before. Also some people said they got graphic problems by reinstalling and messing about with the files, so to make it easy read below ^^
If you want to see the lvl 75 and 80 skill animations for fire mages just download these two files whilst you are off the game.
Put them into your KO folder "C:\Program Files\Knight Online\Data" when you login you'll be able to see the skills like before and you shouldn't have any other graphics problems this way.
*thanks to DarkMag for the two files
