Migrate HUD assets on 1 project to another, HUD won't work

Hi, so I tried to CREATE a NEW HUD project using some assets off the Ue4 store. Now I am trying to get that same HUD to work in my own project, but the HUD never pops up on the new LEVEL/PROJECT I have. I kept the Map Mode setting the same, but maybe I need to change those? Or what else do I need to change in order to get the NEW HUD working and I am using Blueprints. thanks
