My first thing to suggest would be to move the game folder to your desktop, and then run it. It might be that the filepath is too long wherever the game is currently, and so it cannot properly load things on startup. If moving it works, you can then try moving it somewhere else, or rename the folder it was in to be shorter, to try and fix that. If that doesn't work I can check to see if there's other possible issues. Does any audio play when it starts with the black screen?
