fatal error missing file help pls

I’m very new to the ark dev kit and I’m following a beginner tutorial but when i try to load PrimalGamaData_BP I get a fatal error saying it’s missing File:H:\FearEvolved\Engine\Source\Ru . The thing is, i don’t even have a H: drive so i don’t really understand what’s happening or how to fix it.
i’m verifying my files right now in the meantime but it’s taking ages so i thought i would ask in the mean time to people who might know.
