I have photoshop Adobe creative cloud.
I have placed a bunch of items in the library. Come check today to see my library, and everything is gone!
How can I get it back?
You might also try signing out of CC, and then signing back in again.
Sometimes the Libraries panel loses the connection with the Creative Cloud server and is not possible access the assets. Usually, open and close the application solves the problem. Sometimes is necessary logout and login again in the Creative Cloud application.
