Would not let me finish game

I got to part 6 and would not me go any farther. Will try to restart game and see what happens.

How do you unlock the game so we can finish

I TOO HAVE THIS PROBLEM OVER AND OVER. I DOWNLOADED TWICE AND THAT HELPED FOR A WHILE, THEN I SENT A NOTE TO YOU AND SENT ALL MY COMPUTER INFO AND GOT A NEW DRIVER, THAT HELPED FOR A WHILE TOO. I HAVE HAD TO PULL THE PLUG ON MY COMPUTER SEVERAL TIMES AND SIGN IN UNDER A NEW NAME AND REDO THE GAME. I AM SO DISAPPOINTED. TH IS SEEMS TO HAPPEN SO MUCH LATELY WITH OTHER GAMES TOO. HAD A TERRIBLE TIME WITH MURDER SHE WROTE. WHAT DO DO NEXT?????
