Need help with Omega Engine

[MariZ]

I'm currently using Omega Engine, and i have a small problem.
When i load a texture or sprite with Texture_Load, i set the transperent color. But when i draw the texture on screen, the chosen color isn't transperent
To load sprite i use :

Texture_Load(ImgDir+'arno.jpg',Player.Sprite.ID,false,1,$FF10FF);

To draw it :

ASprite_DrawSimple(Player.Sprite.ID,Player.X,Player.Y,
                     Player.Sprite.width,Player.Sprite.height,8,1,Player.Frame);

Is there something wrong with the engine, or there is some problem with the code ?
