I am running NLP 3.0.2 on Window with Lightroom Classic 14.2. Whenever I ran to convert black and white negative, it will show me an error message

 ![NLS error](https://canada1.discourse-cdn.com/flex029/uploads/negativelabpro/original/2X/d/dbf6d59719511cc4adb050e13f3ed4ca0eabcf99.png)  
I had already set the white balance with the dropper. This is particular annoying when I have to batch process a roll because this message will show up twice for every single picture that it processes.  
Can someone help please! Otherwise, the product works well and I like the conversion.
