Well, it happens that this has 2 modes of execution, with DirectX 9 and 10.
When I execute the game with DirectX 10 and crashes over time saying that the executable stopped working. The times that takes to crashes is totally aleatory but it will crash surely.
And when I execute it with DirectX 9 it runs perfectly but there's this bar on the lower part of the screen, that takes forever to get full each time I enter the game or minimize it.
