Game Closes after Pressing "Play" on launcher

[Zera]

So I copied another server folder, pasted Melissia Launcher in it und ran "Force Check" - an hour of downloading later it finished.
Now my problem is that afteri press on "Play" the Game kinda opens (Black Window) but as soon as the mouse pointer changes to the ingame one (right before the first menu is loaded) the game closes without any notification.
I´ve tried deleting the "Me1issiaGames" Folder but its still not working.
Any helpers?
