I have owned this game for several years, but never tried the Origins DLC. I had played the original game before, but not in Starpoint Gemini 2. When I tried to play, I selected Run with the Origins DLC, then New Game, but was unable to select Origins under choose scenario.

I read about people having troubles with game pads and joysticks. I unplugged my game pad and joystick, but that did not help. I moved my mouse to different ports and that did not help either. I have played the campaign several times using the joystick and at least once using my game pad so I know those are working. I can also run the Secrets Of Aethera and the Titans DLCs.

Any help would be appreciated!

I found the problem. Text was overwriting the Next button. You don't have to select Origins at all.
