May sound like an unusual and perhaps annoying solution--but have you tried connecting a joystick to the system (serial port? usb?)? If you do that, then when DirectRT sees the 248 code, it should be comforted by the fact that there is joystick attached and let you pass. i.e., This should get you by the initial check and then DirectRT ought not ask you again during the session. Of course the proper solution would be for us to modify the code such that you could somehow turn off this warning. We can add this to our queue, but for an immediate fix, this may give you what you need, i.e., a way around the initial warning. Note that any joystick should work--e.g.,the cheapest radio shack serial port or USB stick you can find.
