Hey I purchased the product and downloaded it about an hour ago. When it said episode 1 was finished downloading, I tried to start playing it, but about three seconds afterwords I received a notice saying 'we're sorry, Back to the Future episode 1 has encountered a problem and must close'. I tried double clicking it and am under an admin account in Windows. Please help. I'm using Windows XP and have never encountered any such issues with previous telltale products.
