Sandy, I didn't have this problem, so my suggestion may not be appropriate.
If you are not to far from the beginning, maybe a "Start a New Game" will correct this.
I just decided to replay the game and started with "Start a new game".
I played some and quit. I then clicked on the Kairo icon to go on with the game and found the same place I just quit from just before.
I verified if hitting the Escape key to get the main menu and press "Return to Game" would bring me back to where I was and it did.
