Heads up. Yesterday, I did an update to PS CC and Lightroom. In Photoshop, I lost the NIK collection and had to download it again. Issue resolved.
In Lightroom, there were some permissions issues for the directories that LR has to write to. I went through the process that Adobe and Apple recommended, but I am not sure if it is resolved. I got the same message, but then the application loaded. It appears that it is reloading all of the directories in my library.
