Ok, so I have been having problems with my new map so I will just list them and describe the issues one by one (I also think this will be a good Q&A for newer mappers):
Launcher wont let me build sounds
Loading screen will not work
Zombie Risers wont rise.
Dogs won't spawn in

Ok so When I try to build sounds with my map (Ugxm_the_room) it comes up with this error (Its a bit long):

Ok I have no idea why it isn't working and i would give gratitude to anyone who helps me out with that.

Ok so the loading screen. I place the iwi file (Or whatever the file type is) in correctly and I get the default loading screen (Activision loading screen)

Then the dog spawner. I placed in a dog spawner and the script struct and the correct kvp's and they wont spawn in at all.

Isn't anything else to add unless someone would be willing to give black ops perks prefabs    8)

Follow the tutorial https://confluence.ugx-mods.com/display/UGXMODS/Custom+Main+Menu+Music

When building mod, just think build fastfile and build IWD, untick build sounds.
