Creative Cloud app won't find new Files location

Dear all

HELP!

I've just installed a new server to which I have moved the folder Creative Cloud Files, which has thus been backing up all my website resources – Muse files, pix etc – to the Cloud.

So I went into the little CC app and set the new location for the folder.

But every time I click on Sync to web, it looks for the old location – which no longer exists – rather than the new one I gave it. Each time I get the message

Creative Cloud Files Folder Missing

The Creative Cloud Files folder located at /Volumes/WORK 3Tb/Creative Cloud Files cannot be found. It may have been moved, renamed, or deleted.

Options:

- To continue using the application without syncing files click "Turn File Sync Off"

- You can choose to restore the folder from the online backup by clicking "Restore"

1. Quit the CC app and restarted -  no change.
2. Quit the Mac and restarted - still no change.
3. Uninstalled the app, re-installed it and re-set the new location - still no change.

Is there a preferences file that I should delete? Or what? I'm reluctant to tamper with any support files in case it "de-subscribes" me from the Cloud programme. But I'm sure there are safe things to do.

Thanks in advance
