Black Screen with No Audio on Launch after Manually Installing the 07th Mod (Game from SteamUnlocked)

The problem: [Black Screen with No Audio on Launch after Manually Installing the 07th Mod]

Reproduction Instructions: [Manual Installation: Information Below]

Mod/Game history: [With a total of around 8 attempts. I first attempted to use the Installer which failed to install properly for being unable to read a steam registry key. Both web or simple methods did not work.
I only played for a brief few minutes, saved and then attempted manual installation.
I first sent the files to the HigurashiEp01_Data folder, without deleting the CG and CGAlt folders which didn't install the mod.
I tried again, but now deleting the CG and CGAlt folders and got a black screen on launch with the menu audio playing.
After I tried reinstalling it "properly" (I think) around 5 more times again, I keep getting a black screen with no audio now.
... My Steps of Installation from following the wiki's instructions;
Delete the CG and CGAlt folders. Send the Graphics patch, Voices, Movies, Steam UI Mod (I tried MangaGamer and GOG as well, I think, which don't work), Update into the Higurashi.When.They.Cry.Hou folder. I extract them and replace their files when asked. I extract the BGM & SE to the StreamingAssets folder. Then, finally, I extract the extract the source code of the patch, and then the graphics and voice patch zip folder last. Launch. Black Screen with no Audio.
Even after deleting my save file around the fourth try and then the global.dat file, it hasn't helped.]
