After further inspection, I found a hidden error message that was occurring whenever the screen went black. It is error message #6, and has to do with refresh rates.

It's very unusual to get any of the older versions of DirectRT to work on Vista and/or Windows 7. The exception seems to be in some rare cases where DirectRT was already installed on a machine that was upgraded to Vista (or possibly Windows 7). Officially, only DirectRT v2010 is considered compatible with either of these post-XP versions of Windows.
