Try using Alt+Tab and run the game in windowed mode such that you can change the settings. I used to have a similar issue like it. Turns out, it was a problem with resolution.
UPDATE: I just re-read your question and are you sure that you don't see any of the settings in-game ? Have you tried re-installing the game ? Have you patched the game as well ?
