I have been selling a font family for over a year now, and just recently received a few emails from users saying they are getting a System Validation Error in Font Book, and are advised to not install this font. It's only happening to a couple people, but I want to fix the problem. The font has always worked perfectly for me so there isn't really a way for me to test whether I have solved the problem or not.
I've read some other forums on the subject... one solution was generating the font with hinting enabled. I checked my settings and this was already done.
Another was properly filling out the Names and Copyright in Font Info window... which was already completed.
Any thoughts would be greatly appreciated!
