delete bin file, mods folder, client mods folder, and config folder. Force update to get a new bin. re-install forge first and start game to make sure forge loads. then install the other mod parts as instructed. Usually the black screen was either META-INF file still has Mojang files in it or forge didn't load correctly.
Yours is a block ID conflict. Easy fix is make a copy of the config folder then delete it.. start game and see if conflict comes back.
