Ragnarok - can't launch

Thread starter #1
I've tried to play Ragnarok singleplayer but always when i want to play it, I click on "Play SingePlayer" then it will start loading, but the next thing which loads is crash, my game tells me an error and i cannot play Ragnarok.. I really want to play it, i have installed al DLC's so idk where's the problem, even i have SpaceWar installed on STEAM. I need help
Thanks :angel:
