I am working on a type specimen book. I recently upgraded InDesign to latest InDesign CC. For a week or so the preflight showed no errors, specifically none yesterday, when I saved the file and closed the program.
Today there are 131 Type Families missing, according to:
The Type Names--in brackets (A)
Preflight Panel (B)
Red highlighting (C)
(One of the missing fonts is Arial.) D shows this particular font in the font folder.
The fonts are in the font folder, but the document shows them as missing. Help.
Rebooting did not fix this. Coming back a day later, that did.
Hey, always great to get help.
