Cannot Add Anything to CC Library - Icons Grayed Out
Hi Everyone,
One of my users is using Adobe CC 3.8.0.310, Indesign CC 2015.4 Release (11.4.1.102) as well as Illustrator CC 2015.3.1 Release (20.1.0) on a iMac Retina 5K 27" Late 2014 Model running OS X Yosemite v10.10.5
The user had been able to add Graphics, Styles and Colors to the CC Library available in InDesign up until 2 weeks ago, when faced with the following problem:

All of the buttons here are grayed out, and I have no idea how to fix it, I have tried the following
- Full Reinstall of all Adobe Products and Adobe CC
- Deleting the files of the OOBE folder in App Support, while logged in and while not logged in.
- Deleting the CoreSync *.db files in CoreSync Folder under Adobe App Support, while logged in and not logged in.
- Logging out of the user's account in CC and signing in as someone else.
- Logging out of the user's account, restarting the PC, relogging into the user's account.
- Restarting the PC.
I'm so out of ideas!
Please help!
