DirectX antialias problem

[Ishtm]

I compiled sussesful Irrlicht 0.9 with working drivers for opengl, directX9, direct8, i tested it with a .my3d model and works fine, one day i decide add antialias to directx9 driver, so i did. I execute program and get:

Was not able to create Direct3D9 dev
Was not able to create DirectX9 devi
Could not create DirectX9 Driver.
Error: Could not load built-in Font.

The code i use to made multisample capability was one here in irrlicht forum, also i tray with one in DirectX9 SDK how is prety much like the other.
My platform is DevC++ with directx9d pack how are debugger versions i guest.

My questions are:
1) There is a posibility i made directx work with a generics functions and extension capabilities are disabled? If not, why without multisample capability the driver works well?
2) Is a problem with DevC++ DirectX9 pack i used?
just like a note: the example of shaders with opengl are disable... that extension doesn't work in openGL.

I don't request a final soulution... only an orientation is ok!
I dont' be sorry for my english, you dont have to be either!

Thanks a lot!
