Update your graphics drivers, restart your computer. If that does not work then just re-install the graphics drivers to make sure that the device is working properly. (clean install using DDU if that still doesn't work)
- Install DirectX again (optional components that are required by FreeSO)
- Update the .NET framework

Apparently also changing the TDR timeout value can help (timeout detection recovery) for making the applicatoin respond in time so that the application can use the graphics device. CAN BE RISKY
