I tried Direct RT by itself and it was exactly the same. Then Direct RT by itself with the resolution set to 1024*768 and it was exactly the same. The file was originally written by a PhD student who has gone on to better things and completely forgotten about Direct RT. If I drop the whole folder/drive path into an XP based computer it just runs. That wasn't possible for the Win 7 computer as the Documents and Settings folder is managed differently.
The other odd thing is the creation of an empty 'Voice' folder in the data folder.

Version is 2008.2.103.1115.
