Material Error with GeneratedUniformBuffers? Cant Create Anything New?

Hey Guys;

Tried looking around everywhere for a solution but to no avail;
I’m getting a weird error upon opening up the material editor, namely [SM5] GeneratedUniformBuffers.usf(1): error: Cant open included file “UniformBuffers/View.usf” #include "UniformBuffers/View.usf

And it goes on; I’ve tried re-installing unreal, cleaning the registry and basically everything under the sun but to no avail.

Im attaching a screenshot as to what Im getting at the moment.
