Hello Guys.

I bought PTA for P3D v4 but when I load it up, I always seem to need to put in my activation key. I also get this error when I try to apply a new preset: ERROR: shader file C:\Program Files\Lockheed Martin\Prepar3D v4\ShadersHLSL\Cloud.fx is not original Prepar3D shader and can't be used
ERROR: shader file C:\Program Files\Lockheed Martin\Prepar3D v4\ShadersHLSL\General.fx is not original Prepar3D shader and can't be used
ERROR: shader file C:\Program Files\Lockheed Martin\Prepar3D v4\ShadersHLSL\GPUTerrain.fx is not original Prepar3D shader and can't be used
ERROR: shader file C:\Program Files\Lockheed Martin\Prepar3D v4\ShadersHLSL\FuncLibrary.fxh is not original Prepar3D shader and can't be used
ERROR: shader file C:\Program Files\Lockheed Martin\Prepar3D v4\ShadersHLSL\PostProcess\HDR.hlsl is not original Prepar3D shader and can't be used
ERROR: shader file C:\Program Files\Lockheed Martin\Prepar3D v4\ShadersHLSL\PostProcess\FXAAResolve.hlsl is not original Prepar3D shader and can't be used
ERROR: activation failed.

 

Any help would be greatly appreciated.

 

Thanks
