16 bits of precision?

[UTSA-APL]

Hi,

Whenever running an example from direct RT I get the following error:

Problem In: DirectX Initialize Sub
System.Exception: Direct3D Adapter does not support a 32 bit, 24 bit, or 16 bit depth buffer.
This sample requires a depth buffer with at least 16 bits of precision.
at (control&A_0, presentParameters&A_1)

Followed by:

An Error has occurred while trying to load a style's font.
The Font: Verdana, was not found or is inaccessible.
Please make sure the following font was not the result of a spelling error, and that it is installed on your system. If the error persists try running the font at different sizes and under a different font family.

Running directRT 2010 on Windows XP with the admin account.

Any help is greatly appreciated.

Thank you
