I agree. I’m a pro customer too and I have thousands of images in my NextGen install which ran flawlessly until it was acquired (and ruined) by Photocrati. I had to disable this latest version just to get my site running again, which means half of my posts are broken since the gallery functions don’t work. Upset doesn’t begin to describe how I feel about this garbage that NextGen has turned into.
I’m going to try reverting back to 1.9 and see if I can get the site working properly again.
