Camera Raw 15 won't display my custom camera profiles (Windows 10).

Camera Raw 15 won't display my custom camera profiles (Windows 10).  I just updated to Camera Raw 15, and it did not preserve my custom camera profiles in the process.  Moreover, I cannot get it to display those profiles after importing them.  The import profiles function reports that they have already been imported, but they are NOT displayed in the custom profiles dialog.  I have followed the instructions at adobe.com for adding and importing custom profiles, and I have restarted Bridge, Photoshop, and the entire computer multiple times, but nothing works to allow me to use my custom profiles, which I need to process raw files from my infrared converted cameras.    I an using the latest versions of Bridge (13.0) and Photoshop (24.0), but apparently I need to revert to earlier versions of these and Camera Raw to use my custom camera profiles.  Please help!!
