Mmm, try one of these solutions:
- Update your graphics driver to the latest version
- Delete everything inside of the folder c:\Users\YourUser\AppData\Local\Changed3D
If it still doesn't work, a log would be useful, which can be found at: c:\Users\YourUser\AppData\Local\Changed3D\Saved\Logs\ (folder should automatically be created when trying to run the game).
