Just recently got the Cameo 3. Had the SCAL4 previously, never used it. When I try to type in my font it's not typing the font. If I click on the fonts in the library it lets me click on the letters for the font i'm using. Does anyone know how to use it so I can type in the words?
TIA

Since you already own SCAL4, the first thing I would do is make sure I have the most recent version installed, just in case it's a bug that's been fixed:
