Thanks Steempipe!

It appears that there is a bug with the paths.. I use a dll to set some of them. Depending on your computer, the "Edit Shader" button may or may not load the shader in SSE. IF that is the case, just run SSE.exe and open userdef.fx (both in the main directory) until the next update.

Also, if anyone has any .FX files they'd like to add to the library, please post them! (or pm if you would like).
