hi, when I try to save a file, or open Installed Fonts, this error message pops up. How to prevent and fix this? I can not save my work just because of this.
Please help, would be appreciated 
First make sure you have the latest release. As of this writing it is version 5.6.
Also make sure your copy is legal, as we know of several illegal downloads of our software that do crash due to added code containing viruses and trojans.
