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.
