Installed Fonts do not display in Photoshop

I downloaded some fonts that I need to crate an ad and they show as installed in my fontbook (even display as a font option in Microsoft Ofice) but I can't use these particular fonts in any of my Adobe applications. Does anyone know what may be causing this and/or what I can do about it? Any help is greatly appreciated. Thanks.

put them in the Adobe font folder.

Even if they go into the system folder, they should show up the next time you launch Photoshop.

It sounds like the OS font cache is out of date, and CoolType (Adobe's type management code) doesn't know that fonts have been added.

Which means, clean out your font caches.
