I'm doing "In the Beginning Part 2" now. Setup and part 1 didn't go entirely smoothly (for example, running with Steam), but I managed to get the purple box. With part 2, I managed to change the texture of the box, but then the map exits immediately (the game doesn't get into it at all). I suspect (though have no way of knowing) it's because the texture is 80x80 (there's no way I'd be able to select the texture you mentioned, because the drop down list cuts all the names -- so I just picked one that starts the same). I tried to change the texture, but now I can select only one wall at a time. The tutorial said "Select your cube. Only got one wall? Click on the Ignore Group button." The button doesn't change a thing. What do I do?
