Error #: 7
Function: GpuProgramParameters::getParamIndex
Description: Cannot find a parameter named eyePosition.

15:32:46: Error in material Examples/Athene/NormalMappedSpecular at line 1095 of Examples-Advanced.material: Invalid param_named_auto attribute - An exception has been thrown!
I have check the OgreGpuProgram.h file, there is no paramater called eyeposition or something like, only ACT_CAMERA_POSITION_OBJECT_SPACE.
eyePosition is a parameter name in the shader, not an auto type. This error means that you have an incompatible version of cg.dll on your path; we provide cg.dll v1.1 with the Ogre dependencies which definitely works, this issues can occur with 1.3 beta and has been reported to nVidia (although with no response in 4 months despite follow-ups).
