Typekit fonts? Your own fonts? Exactly which fonts? Operating system?
Thank you for the reply Steve. I am running Windows 10 Pro and a mix of Typekit and my own. I don'e even know all the fonts, it's almost like it reverted to the basics.
The Typekit fonts might disappear if you were not logged into your Adobe ID. Go to the CC desktop app > "gear" icon > Preferences and sign out and sign in using your Adobe ID.
