I looked through my files, all were present and none were copied. That's not the issue, I don't think.
Alpha Mask is turned off for the terrain file. Regardless, I only have control over two of the map's terrain images because I made them, all the other custom maps I couldn't change. That doesn't seem to be it.
Looks like I'm uninstalling and reinstalling. Thank you, Cloudfish (and no, its YOUR MAPS FAULT D< ) I'll back everything up. I just have this lingering fear since I had tried to transfer a lot of my files from my old computer to my new laptop and things just wouldn't work no matter how perfect I got them and preserved them. But there's no use fussing over something I might lose forever if I can't even use them now. I'll update if it works for all others trying to solve this issue too.
