Hi, I originally downloaded, installed, and played episode 1 of the game (as well as downloading, but not installing the other 4 episodes), back when my desktop was Windows XP. I now have a Dell Windows 7 desktop machine, and was able to transfer all my old files to the new computer, but not the old programs. I reinstalled ep 1, and installed eps 2-5. I tried to play episode 1, but I just get to the opening screen, where it says in the top right "It's About Time" and "Marty travels back in time to save Doc's future!". Below that is an animated drawing of Marty seeing the delorian materialize, and a "Play" button below that. All 5 episodes are listed on the left side, each one saying the episode is "Now Available!". I press "Play", but nothing happens. When I see the other episode buttons, where the "Play" button was for Episode 1, I see a "Get It!" button. What's going on? Please help me fix this problem.
