I'm also having the 'color scheme has been changed to windows basic' problem on Win7 with a Nvidia 8800 GTs,after installing the patch. The error meaasge says, "you are running a program not compatible with certain visual elements of windows".
I have unchecked the 'user interface in desktop resolution' box but it did no good.
The game works fine and there are no problems with the graphics that I have noticed.
Win7 goes back to normal settings when I exit the game.
That's all by design, the black screen issues were caused by Aero, so we disable it when the game starts. You can disable windows 7 issuing these messages though. Right click in the task tray, choose 'Customize notification icons' and disable the messages of the desktop window manager.
