Game Launcher

Have a small problem, Have licenced version and been using for years.

I play ACC but today I thought to give AMS2 a go, Started game from the Dashboard and all went OK, Finished playing and come out, Now when I went to launch ACC again the game box come up like it should but then AMS2 box comes up and I can only start that.

 I deselected all games in the setting and only selected ACC but it still dose it, Basically at the moment I can only launch AMS2 from the dashboard
