Happily Adobe are aware of the problem and have released a fix which you can read about here.
If, like me, your Creative Cloud app isn’t aware of the update yet then simply go to Photoshop’s help menu and click on Updates…
Recovering Your Lost Preferences
Of course the fix doesn’t help restore your lost Photoshop preferences so unless you have a backup of your preferences files or have used Photoshop’s “Sync Settings” feature then you’ll have to restore them manually 😦
Luckily I always keep a backup of my Photoshop files (see my previous post “Restoring Photoshop Settings” to discover how to do this) but I’ve never actually looked at how the “Sync Settings” feature actually works.
Photoshop’s “Sync Settings” Feature
I suppose in the back of my mind I just assumed that my Photoshop preferences would miraculously be backed up to my Creative Cloud account and I could retrieve them any time I wanted to either of my computers.
The reality of Photoshop’s “Sync Settings” feature however is a little different and requires manual activation before anything is backed up to the Cloud. Having read up a little on how the “Sync Settings” feature actually works I highly recommend anyone using Photoshop CC go and set it up asap.
To find out how to use & manage the “Sync Settings” feature read this blog post by Richard Curtis from Adobe.
Don’t limit your backups to your valuable images and documents, make sure you backup your configuration files too.
Always take advantage of online backup solutions when they are practical but don’t blindly trust in them, always keep your own backups as well (just in case).
