After doing an incremental update from AECC 2014.0.0 to AECC 2014.0.1 the Sync Settings dialogue doesn't work.
After clicking on ‘Sync Settings’ I get:
‘Authentication failed. Check network connection, Adobe ID, and password. Please try again’.
After checking all of those things (network, password etc) I try again but there's no change and I get the same error dialogue again.
I then tried ‘Use settings from a different account’ but still using my existing Adobe login details but I still get the sync dialogue error message.
What's the story morning glory?
Running AECC 2014.0.1 on MacBook Pro - 10.9.4
I have exactly the same issue and error message, whilst clearly logged in to CC (the AE main menu shows I'm logged in and does everything it should when logged in apart from sync my settings).
It's clearly an issue at Adobe. There was a similar problem last year which affected Premiere too.
