Hi! That fix is specifically for a black screen on Zhara's ship after having played through chapter 13, and that bug was fixed in a previous update, so your issue is something else.
Since you get a black screen also from starting a new game, what I suspect is that the modded version you made wasn't installed correctly, whether by you running out of disk space or cancelling the installation before it was done. Try deleting the modded folder in Didnapper 2/mods/installs/ and installing it again through the Mods menu, and let me know if that fixes it for you.
