Hi @iancawood

A few things to try (in order) to figure out what has gone wrong:

1. Try [resetting your Lightroom preferences](https://www.lightroomqueen.com/how-do-i-reset-lightrooms-preferences/). After you reset your preferences, you will need to go back into “file \> plugin manager” and add back in the “NegativeLabPro.lrplugin” plugin. If there is an issue with metadata or conflict with another plugin, this should clear it out.
2. Try restarting Lightroom Classic, and importing completely “fresh”, untouched negatives. See if Negative Lab Pro will work properly on those fresh negatives. If that works, there could be a metadata issue with the existing conversions.
3. If that still doesn’t work, try creating a new catalog in Lightroom, then add fresh negatives, and see if those convert.

Let me know if any of those enable you to open NLP.
