I have been modding with 7th heaven only for a short time, and this seems to be the only issue I have been unable to find a solution for.
When playing the game after installing the mod in question with 7th heaven, I noticed an issue where the character backdrops in the menu appear as solid black squares, and the opening cinematic with the credits and logo is the same as well. The title menu as well is black, with only new game and continue as options. The eidos and square logos on startup are completely fine though.
