Okay so i tried with another account still the same issue. I'll try to explain how i made the server then maybe you know why, 'cause i didn't do any client side let me explain.. I follow this entire video : https://www.youtube.com/watch?v=TaESjeq2v-w wich have been made by someone of this community and everything went perfectly. now the thing is, as it don't explain client side and that my knowledge about this are near nothing i just downloaded: kRO Full Client 2014-08-22 extract it, made the sclientinfo and launch my server with the lancher already in it. So basicly i don't know how to diff or what kind of file i need to diff etc. But even the way i did i managed to play around 3 days even when i put it online so i don't understand why it crash when i get in the game.. specially that the server is running like a charm, no error.. Maybe if you could find something that explain me exactly the steps of the client side i could make another one less bugy ? i tried but i don't find something with the links etc..
