Looks like a graphics driver problem.. how much video memory do you have ?

The display driver is responsible for implementing DirectDraw support, if the display driver doesn't have the correct functionallity, the DirectDraw middle-ware will return the failure you're seeing. If you control the display driver, you can add DirectDraw functionallity, though it isn't trivial.

RGB Emulation looks enabled. Try disabling it.

Unfortunately RGB emulation appears to be the only driver mode found during enumeration. So it looks like your computer may not have the specs required to run Orbiter. Even if you could get RGB emulation to work, the frame rate would probably be prohibitively low.

Do you encounter this problem only with the beta? Does the 2010 version work?

Do you know what graphics hardware is installed in your PC? Are you able to run other DirectX based graphics applications and games? I guess it's unlikely, but it could be a driver-related problem that prevents hardware modes from being enumerated (possibly because DX7 support is now becoming sketchy). If you suspect that this is the case, you could always try the DX9 client, which should have better driver support.
