CC Libraries — File does not exist / is in use / don't have access — Problem
Just today i received the problem that i wanted to pull an .ai file from the libraries into an InDesign document and it gives me this error message (german, sorry)
"File does not exist / is in use / don't have access"

The file is neither of the mentioned issues. I even can open and edit it in Illustrator and view it on the website library.
Also, InDesign suddenly tells me that certain library files, already used in other documents, do not exist anymore when i open the document.
What can we do?
Cheers
