I recently upgraded from lr4 to the current version with cc. It's been working great up till today. Lr no longer connects to the Internet. I can't sync or even start the Adobe manager. Keep getting error code 1. I can sign in but my sync folder won't allow me to move anything into it. I also noticed that my HD status reads setup.
I run a MacBook pro.
If you have any issue launching and running the Creative Cloud App Or getting error code:1, please refer the below troubleshooting link.
Let us know if that helps.
