Equipment turns Invisible when Equipped

[Shade the feline]

Hello. I'm relatively inexperienced with running mods, and I'm having an issue - I believe with Devious Devices/Bodyslide - where many pieces of the equipment becomes invisible and turns the part of the character it's being worn on invisible as well. 

When I installed Bodyslide I selected the options "Bodyslide”, “CBBE”, “Pre-built CBBE HDT + Morphs” and “RaceMenu Morphs for CBBE".
I have Devious Devices - Assets 3.0, Integration 4.3, and Expansion 4.3. I have all of the pre-req mods for DD.
After installing all the mods I ran FNIS for Users, then ran Bodyslide 64.
In BodySlide, I selected my CBBE preset, checked "Build Morphs" then did a batch Build using CBBE - HDT as the output. I also clicked the big Build button once this was done, then saved and closed BodySlide.
Previewing the items in Bodyslide show the form of them - My understanding is that this is the mesh - but they're plastered with "no image" Signs.
I've spent a few hours trying to work through my files, reinstall the mods, and look at Bodyslider tutorials, but I feel like I don't have the experience to make educated guesses on how to fix this. Is there any information I can supply or anything I can do to get this fixed?
