When I try to run the game I get a popup that reads "ERROR Graphics card does not support shaders". I have a GTX 970, so I figured something else is causing the error, or can I just not run the game with a 970?
That may indicate your driver is out of date for the graphics card, see if you can upgrade it. If that doesn't fix it, then something strange is going on... Do websites like https://www.shadertoy.com/ work for you?
