Please remove old theme from Aero folder and delete the .theme file and add the new pack directly to the theme folder
Always Create a System Restore Point before making any Changes to Your PC.
This is nothing special, just changed the global colorization color to get rid of the grey inactive windows and changed the title text colour to white so you can use black borders, sorry not good for white borders but if you want white borders just use the normal aero style.
You will need to download and install UxStyle Core Beta for windows 8 to use this theme, just extract the theme and put the msstyles file in the aero folder "C:\Windows\Resources\Themes\aero" and the theme file in the theme folder "C:\Windows\Resources\Themes"
I am working on making proper themes for Windows 8 but waiting for some better tools to hack it up a bit more first.
I have managed to move the details pane back to the bottom though (where it should be) if anyone is interested I will show you how.

OK well not sure why you would have a black screen then, I have almost 6 thousand downloads and I have not seen anyone else mentioning black screen problems, maybe you did something wrong, my first release of this theme was meant to go in the default aero folder and that was the cause of the black screen bug I mentioned, I then uploaded a fixed version that went in it's own separate folder, I am just wondering now if you have misunderstood my instructions and done something different.
