Camera Profiles not available in ACR?

Hi there,

I have recently upgraded my camera equipment to a Nikon full frame and associated lenses.

Now, when I process my images in ACR, the s/w does not recgnise the camera or lenses and they are not in the dropdown list.

I have checked the C:/ProgramData/Adobe/CameraRaw/Cameras and LensProfiles and they are all there.

Is there a way to reset these in ACR or to get ACR to recognise these new cameras/lenses?

All of the old profiles still work fine and are recognised.

Thanks
Graham
