It was designed to be used on Graffiti v1 devices, which went out of style over 5 years ago in favor of G2. They never updated the game for this later version of Graffiti.
Mala, if you're having trouble with Graffiti and accuracy rates or simply don't like the characters they're giving you, I swear by this . . . allows for all sorts of macros (simple symbol for "the," etc) - and allows you to make the strokes how YOU want them. http://www.tealpoint.com/softscrp.htm
Just throwing out as a possibility - you don't have to train yourself to use what you're given - you can make up your own that work for YOU. It's invaluable to me.
