Hello!  
I’m a nearly brand new user. I installed NLP on my desktop and just now installed v 1.3.1 on my laptop. I entered the license key, but it is only allowing me 12 (total) conversions on v 1.3.1. The (older) desktop allowed me to use the key without issue. ![41%20PM](https://cdck-file-uploads-canada1.s3.dualstack.ca-central-1.amazonaws.com/flex029/uploads/negativelabpro/original/1X/b721c07ec651270968d6261dec047bc2a7d3fdae.jpeg)

> Problem: “I entered my Negative Lab Pro serial key into the Lightroom plugin-manager. It appeared to be successful, but then when I try to use Negative Lab Pro, it is still in trial mode, and I see my remaining uses counting down.” Solution: First, make sure you have the most recent version of Negative Lab Pro. Then, follow these steps to force Lightroom to keep your Negative Lab Pro registration. Exit Lightroom Hold down Shift-Option (on Windows it’s Shift-Alt) as you double-click on your…

The newest versions of Lightroom seem to be causing some issues with saving the serial. I’m seeing if there is a way to make this more stable, but in the meantime, you can follow the article above.

I installed the previous version of NLP with the key and then reinstalled the v 1.3. after it and it looks to be running without any trouble.
