I was using NLP in Lightroom the latest version, I had done about 8 converts when all of sudden Lightroom froze up. I then restarted lightroom and then the run the hotkey for NLP, but everytime I try to run the NLP with Ctrl+N my LR freeze’s and even when I quit the NLP plug-in LR is still unresponsive . I have treid to copy all the files again for NLP to the original install folder, I have disabled my GPU for my graphics card. I have also tried Windows System restore all to no avail. I copied my catalogue over from my desktop to my Laptop and it all works fine on that pc, but nothing I have tried works on my desktop. Windows 10 updated, running the latest LR Classic, and the latest version of NLP. Anybody got any idea’s I can try. MJ. ---

Hi, The first thing I would try is **resetting your Lightroom Classic preferences** , which is shown here: [How do I reset Lightroom's Preferences? | The Lightroom Queen](https://www.lightroomqueen.com/how-do-i-reset-lightrooms-preferences/) I would then try reinstalling Negative Lab Pro, following the README file in the download. For Windows, it’s important that you place the NegativeLabPro.lrplugin somewhere that you definitely have full admin rights to and is on your main harddrive (I recommend creating a “Plugins” folder on your main C:\ drive, and placing NegativeLabPro.lrplugin there). ---

Hi Nate I upgraded today and I used the hotkey to convert my negs, I had a 4 hour session and up to now all went smoothly and it seems faster, well done and great work for a fantastic program .
