Oh my god, thank you. I was right in guessing I'd missed some crucial obvious step. I was going under the false assumption that the data folder always had a textures folder and that my version had that in bsa format, as opposed to having to create a textures folder on this fresh install. Then when it wouldn't connect through my own folder by a different name I didn't think that it was the folder name that was the problem. I got my pipboy icon into the game no problem now. Thanks again.
