NLP Profile Missing

Hi, I use VueScan and a Canoscan 9000f for scanning. Every time I import a Vuescan DNG, I get the error message that the NLP profile is missing. I update Vuescan DNGs, read metadata from file, and restart lightroom, and the profiles are back and things work well. I’d really rather not do this every time. Just wondering if anyone else has encountered this same problem.
