What is your OS? Do the fonts show in other programs?
What does it mean that you "installed them on my computer correctly"?
What OS do you have, and what did you do to install the fonts? Where are the fonts on your computer?
I am having this same issue.
I have installed new fonts into font book, and on going into Indesign to put them into a document they don't appear correctly - the font name appears in the menu bar with brackets as if it is not installed. When I do the same in Illustrator however it displays correctly.
I have trashed my preferences, rebooted program and computer...
I have also copied the font files into the Indesign/Fonts folder.
These fonts are expensive and I need them for an urgent job for a client...
Hoping someone can help! :-)
