Joe,
If you’re having the same problem as that player (black screen when you launch and the game crashing immediately after) you should try the same steps that fixed things for them.
If you’re still having trouble after this troubleshooting, please generate a text copy of your DxDiag using these instructions. Once you have that made, open the file. Copy the code below, then copy/paste everything from that DXDiag file between the rows of tilde (~) marks where it says “DXDiag goes here.”
