I looked at this page before I posted and I don't have a Program Files\Common Files\Adobe\Fonts folder.
It looks like this page is from CS5? I'm using AE CC 2014.
I couldn't help but chime in... I like the name.
Sounds like you're on a Mac: they make it tough to find that folder referred to on that help page. I think it begins with the OS hiding the Library. You have to go on a hunt.
No I'm running Windows 7. They must have changed the font directory settings for AE CC 2014? I'm not sure how to cure this but I do need to get it cured since the template font style is different than our corporate font.
Where, exactly, do you have the font installed now such that Photoshop is able to use it?
Dave I had a similar problem today (I see this is an old thread but hopefully this might help others).
I had a font installed and working correctly with Premiere Pro CC but when I opened After Effects and tried to create a text layers using the same font only the 'Black' version of it appeared in the drop down list. I tried reinstalling the font, installing it directly into the Adobe folder and rebooting the machine a few times - none of which worked.
The solution in the end was to uninstall the 'Black' version of the font and hey presto all the others magically appeared in the drop down list!!
Hope that helps somebody!
