Oh, I see. Well, usually when you start v37 up, it comes up with three windows. One for the game displaying on screen, one for the code and all that in a little black box and one to select a level from the different compatible levels. Make sure they are compatible with the modern Windows version and don't go into the original unaltered files, they won't work. Select a level and then, boom, it's running. Also make sure you're using a Windows PC, and not a Mac, Chromebook or Linux. If you already have tried this, then I really don't know what's happening.
