Update:
Concerning the D3DCompiler_47.dll I did a little studying last night & I know now what this file is for so I'll remove this from the context.........for now (necessary for the game client's Dx9.x graphics coding to function correctly within Dx11 API.....).
So, unless the issue is found, the last resort will be for the game client to be totally rewritten for full native Dx11 functionality..........which would actually be IMHO the next logical step to take from my perspective and retire the Dx9.x code entirely..........but Hitech may see it differently.
Would be a LOT easier to do if the current version w\ the HLSL shader compiler was functioning clean.
Continuing w\ testing.................err, playing............
