I get this error if i try to run rohan while running blade and soul (another game with nprotect/gameguard) gameguard sees itself as a hack, so if u have anything on that runs on it u cant launch another. Its weird tho that he can get to character scree,normally canr even start the game at all if so.

If he do not have anything else running i would suggest reinstalling... I dont know what have happened with this game but I have to reinstall every morning to be able to play now :/ and they wont answer my ticket either, any of them... I hve a few up for different things, bugs in game, items missing, and the loader being fwaked, none been answered, been 2 weeks now. Dont know wtf is going on
