I have a problem with cc libraries across all apps, i mainly use Indesign, Photo and illustrator.
I can create a new library and can add assets from the market place to them, but i cannot add colours, or any items from the page into it. or even previously created libraries.
The colours problem is my real beef, i use this function a lot as its useful for for consistency across the apps. This has been a problem for a while, then last week i got a brand new Mac Pro, with all the apps freshly installed. the problem went away for about 5 minutes, then started again, and i'm back to not being able to add colours etc.
I am also having the same issue. I've also uninstalled and reinstalled, plus I've cleared the firewalls and reset permissions.The Libraries window looks normal, but the icons for adding elements are greyed out. If I drag and drop, the window darkens as if accepting the element, then does nothing. If I'm in indesign and try to use the color theme tool's beautiful add to library button, nothing happens. In photoshop, clicking New Library from Document also does nothing. Below is a screen grab of Indesign, Illustrator, and Photoshop open. You can see the greyed out icons. You can also see that they were working fine until 3 weeks ago, when I installed the latest updates.
