Fonts in OSX
If your Adobe programs quit or get stuck during start-up quit or force quit the program. Search for any files named "adobefnt" and delete the files that end in ".lst", then restart the program.

Other programs, such as Quark XPress may need the OSX font caches cleaned. There are a number of utilities that do this; freeware utilities such as "Onyx" can be found at:

or DTP Types "Font Aware" which will remove the Adobe font cache and the System font cache.
