Fonts are activated at a system level. If you’re not using Suitcase anymore to activate fonts, then you’re either installing fonts in your OSX font folders, or synchronising them from something like Typekit. It’s then down to applications to check the OS for active fonts.
If you think you have installed fonts that are missing then that’s a question for Adobe Technical Support, since you’re not using Suitcase. You can check in System Information to see if the fonts are listed there as installed, and check other applications (e.g. TextEdit) to see if they appear in the menus there to isolate that it’s an application specific problem. If so, it could be your Font Caches are corrupt. Of course Suitcase has a feature to clean font caches, but reinstalling it probably isn’t an option if your trial expired, so you’d have to look for alternatives or purchase the software.
