Does the black screen come up when you try to INSTALL Vortex, or when you try to RUN Vortex? What do you do after that? Most likely if you're using Windows 10, the screen goes black because it's going to bring up the popup asking if you want Vortex to make changes to your computer, so then you click "OK" The black screen occurs when i try to launch vortex. I can get to the letting the computer make changes and click ok. But when i try to launch the program the screen it comes up with is black
