Episode 3. Can't unlock vault. Even though I achieved 4 stars in the hotel room and the casino, I don't have enough stars to open the elevator. It says I have only one star in the elevator scene and that won't open it. In a be replayed hotel room and casino many times, but nothing opens. I can't advance. I'm totally locked out.

I completed the first two scenes of episode 3 and got 4 stars on each one. The last star is locked. I can't open their elevator scene. It says I have no stars. What happened to the 8 I earned in the first two scenes? Why can't I move forward? Does this mean I'm done in this game? I can't unlock anything. I'm locked out.
