If you have successfully unpacked and installed the fonts, but the fonts are still not available, try the following tips:
1. Some applications need to be restarted after new fonts are installed. Quit the application and start it up again to see if the fonts are available afterwards.
2. Scan the entire font menu. The font may not be where you expect it to be. For example, in Mac OS X, the order may not be strictly alphabetical; some fonts may appear at the end of the font list.
3. Restart the computer. This simple action often solves a number of mysterious problems.
4. Check a different application to see if the font works there. Some software may have special requirements for font installation, so consult the manual.
5. Reduce the number of installed fonts. Having too many fonts installed can create problems.
6. If you use fonts in Adobe applications (InDesign, PhotoShop, Illustrator), and the fonts are missing or appear corrupted, search your computer for all copies of the file AdobeFnt.lst (for example, Adobefnt01.lst ... Adobefnt12.lst) and delete them. The easiest method is to search your hard disk for all .lst files. Delete all found files, and then restart the Adobe application.
