Resource Packs Refuse To Work Correctly

I'm trying to use the texture packs City and Fantasy in my worlds, and I only have them because I previously owned them within the lifespan of Minecraft: Xbox One Edition. However, whenever I use them and attempt to load into my world, it will tell me it could not load in the resources or textures for the pack and for me to uninstall and reinstall, and then restart Minecraft. Even after doing so, I still get the error. This is irritating me. I would like a fix to this so I can use them again!
