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.
