I've tried to edit a very small amount of text in a PDF created with InDesign 4, but although I can select the text, it won't let me edit it because Acrobat 10.1.4 claims the font isn't available. But it is available, because it's included with one or more Adobe applications that are installed on the Mac I used to create the original.
What gives, and how can I gain the ability to edit that text, without having to change the font in the original?
