Adobe DNG Profile Editor and LR5.7.1

Jan 11, 2013
Lightroom Experience

LR 5.7.1
Operating System
Windows 7
I recently bought a used converted camera to try out infrared photography.
I've tried using the DNG Profile Editor to overcome white balance restrictions in LR.
The Profile Editor tells me it has exported the profile I have created but the created profile will not appear in the Camera Calibration section.
When I check the profile that has been created the file is only 1kb in size. Other profiles for that camera that Adobe has created are 110kb.
I have downloaded the DNG Profile Editor a few times thinking it was a problem resulting from a faulty download but it is always the same.
Is anyone having any joy in using the DNG Profile Editor?
