Since I've been burned before, I decided to wait awhile till I updated my Lightroom 2015 to LR CC Classic. (A stupid name that, to me, spells doom for the desktop.) Anyway, since I updated to the latest version earlier this week, every time I launch LR, I get a "Server Busy" error message which I need to then click to get rid of. This is regardless of what catalog I launch. (I use different catalogs for different purposes: one for my portfolio, another dedicated to travel, and multiple for different shoots -- each shoot gets it's own.) It also matters not whether I am using a "local" catalog on one of external drives where the images reside or a catalog where the LR database of my computer, but the image files are on a NAS drive.
I run Windows 10. Has anyone encountered this? Thanks.
