Ok, updating the above post, I'm still not able to get it to recognize the disk. I've tried everything listed in here, but nothing works. When i run as a user (rather than admin), the game crashes, but with no error messages. It just stops and windows goes off searching for a solution, which it can't find. If I run as admin, it fails to recognize the DVD. I've downgraded to D-9, run with and without the options.ini file, etc, etc etc...
Any suggestions?
