Illustrator keeps switching fonts back to Myriad Pro in mid-document-why, and how do I stop it?

[birckcmi]

I went out and bought some fonts on my own a few years ago-actually paid for them-but when I try to use them in the latest version of Illustrator, any carriage return will switch back to the default, Myriad Pro. This is pretty infuriating. How can I stop it for good?

Ah-ha, Thank you!

I'm glad you could solve it.

There have also been updates that tackled this problem. But there are currently reports that some people cannot print with the updates.

I was 100% with you until that wild and inappropriate generalization you ended on. 

[Larry G. Schneider]

Are the fonts you purchased OTF fonts, True Type or Postscript Type 1. If they are PS type 1, they are no longer usable in Illustrator.

For me the problem arose when adding fonts from Adobe fonts.

Estoy teniendo el mismo problema, y tras varias llamadas, a través del chat me han confirmado que es un error ya reportado, pero aún no solucionado.

Esto no pasaba ni con los Mac's en CGA.

Como siempre, la alternativa es bajar a una versión inferior hasta que se solvente.

Pero son demasiado los fallos que siempre muestra la suite día a día.

Turn off Missing Glyph protection in Preferences > Type

[KREA]

al desactivar esa casilla, parece que ahora no cambia de fuente.

Gracias!

DISCO!

[Tommy5C13]

This just now happened to in the, as of writing this, the latest version of Illustrator. Feels like I have a ghost in my computer!

[Monika Gause]

Turning off Missing glyph protection does not help?

[Tommy5C13]

That seemded to work, thank you. The problem arose when I added the typeface Metronic Slab Pro Semibold from Adobe fonts.

I found this solution elsewhere but worked for me...... goto Preferences -> Type -> turn off the "Enable Missing Glyph Protection" OFF.  That seemed to fix my font reverting issue.
