Game launched, but it appear on my task manager... that's all, i can't play it... Any idea ?

So, i installed everything, and when i launch the game, it appear in my task manager, but the game is not giving me any window or something similar to play, is it normal ?(i guess not) and if not, how do i fix it ?

normally that happens when Gameguard doesn't open, check if your anti-virus is not blocking it or another program is having conflict with it
