I also have the same problem.
When you have problems with CC Libraries, this often fixes the problem:
Go to the Creative Cloud desktop app (found in the Menu Bar on Mac, the Task Bar in Windows). Click the "gear" icon > Preferences > General. Sign Out, then Sign In again with your Adobe ID.
Works fine now, thanks Steve
Hello everyone, some other solution ?
I have the same problem , I logged out of creative cloud , I closed CC Libraries from operating activities but nothing.
Please start a new conversation by providing more information about your problem with CC libraries. What operating system? What version of InDesign? Exactly what problem are you having.
Thanks, I have Windows 10 and the latest version of InDesign CC, REALISE 2015.2.
I have the same problem encountered by INDIGOSANS, we created a library by illustrator, with different graphic elements and suddenly stopped working highlighting the error mentioned in the first post. I see the graphic elements but can not use them.
I tried to get out with Creative could log out, close the windows management activities of the process CC Libraries but still not working.
Thanks for the attention
It may be a Windows issue, and I work on a Mac. Maybe one of the Windows users can help you out.
Both me and my colleague use Mac and have the same problem.
Have sign in and out, but still gets the same message.
