RO2 and Bishock 1 not running in Bootcamp

Hello,

I recently installed Windows 7 64 bit through Bootcamp on my Macbook and I can't seem to run certain games on it through Bootcamp. The games in particular are Red Orchestra 2 and Bioshock 1, both which I thought (read: hoped) would be able to run. When I launch either one, nothing happens whatsoever.

My macbook is this model:

and I am using Snow Leopard. Other relevant information is that I installed the Bootcamp drivers from my original Leopard install disk (the one that came with my computer). The drivers seem to be working as I have sound and all the function keys are working.

Finally, when I looked into the launch log after trying to start RO2, the last two lines read this message:


[0001.83] Critical: appError called: Alpha blending with D3DFMT_A16B16G16R16F is not supported, which is required to run this game
[0001.83] Critical: Windows GetLastError: The specified module could not be found. (126)

Does anyone know what this means? Any help would be greatly appreciated!


Thanks in advance,

David
