I FIGURED IT OUT!!! YES! YEEEEEEEEEEEES!
Alright, major thanks to silmarill_SVK for his suggestion. Do exactly as he says, and if the game crashes when you try to open any of the maps, or for that matter, even the options, I KNOW WHAT THE ISSUE MIGHT BE! It's even mentioned in the readme! Windows has a service called DEP, which stands for Data Execution Prevention. Basically it stops programs from accessing your computer's memory in ways it shouldn't. What you're going to need to do is add keeperfx and keeperfx_hvlog to that.
To do this, you need to go to the start menu and right click on my computer. Select properties, then the advanced tab. The first thing you should see is Performance. Click on the settings button, then click on the Data Execution Prevention tab.
Now, you can actually opt to turn this off for all programs except windows programs, but it's probably a safer idea just to click add, go to the folder where Keeper FX is, and then add both keeperfx and keeperfx_hvlog. (You'll have to do this one at a time.) Once you've done that, hit apply and YOU ARE GOLDEN! I can confirm this works for me! YES!
Thank all involved :) After installation, game crashed when loading in-game screen. This was a very quick fix. Very grateful.
