Missing Font issues in InDesign

When you "activate" fonts with Adobe Fonts, you don't so much install them like you actually have/own them as you lease access to them. You're not "downloading" fonts; you're gaining access to them.

This causes complications, especially in instances where you formerly did have downloaded fonts (or if you're really ancient, loaded them into your system on some kind of disk) installed. While this is technically debatable – you do download files related to those given fonts on your computer – It's not like your system recognizes those files as fonts. You need an online connection and active sign-in to Adobe to access those Adobe Fonts files.

For the original poster: You've got to 1) maintain that online connection and live sign-in to access your new Myriad Pro fonts, and (likely) have to 2) change all instances where you used the previous Myriad Pro fonts you owned and removed from your system. They may look like the same font(s) you owned and removed, but as far as your system is concerned they're different fonts. You'll need to reconcile the discrepancy for any document where you used the previous cuts of Myriad Pro you owned and subsequently removed from your system.

For you, ebargains, you shouldn't have to re-download the fonts. But you'll absolutely have to be connected to the internet and actively signed in to Adobe to access the fonts.

Hope this helps,
