It happens to me from time to time but I just wait and keep pressing ENTER.What to do when this black screen appears in the game?
I've found that this game freezes quite frequently. Maybe the packaging of the (huge) EXE causes trouble while loading resources? It's my sole complaint so far. It took me a while to get it started because I first got the error because the 'save' folder didn't exist and going back to the main screen isn't worth the trouble of waiting, so I'd quit the game and go on to try others before going back to it and (obviously) forgetting about creating the folder. Rinse and repeat 2-3 times.
