I'm opening a PDF created with Adobe Illustrator CC in Adobe Illustrator CS6 and other than some features may not be available warning, it complains about a missing font:
The font TrendRoughSlabOne is missing. Affected text will be displayed using a substitute font.
However, I did purchase that font, but it shows up in the Illustrator Font menu as
Trend Rh Slab One.
How can I instruct Illustrator to substitute and use this name variant instead?
