I keep getting a small pop up error message after the updater finishes and VO starts to load. The message is 'Choose Pixel Format Failed'. So I am thinking one of my settings must be incorrect. Does anyone know which one I should change to eliminate the error?

Make sure you are using the DirectX 9 Video driver and not the OpenGL driver on startup.
In your config.ini file there should be this line in the [Vendetta] section:
VideoDriver=DirectX9 GKGL driver

If you have this line instead:
VideoDriver=OpenGL Reference GKGL driver

then change it to the DirectX9 one and try that.

Thanks Ray! I think making that change got it.
