What is interesting for me is that I have SharedMediaAdditionalFonts and I can use other fonts only on one of my characters, on other characters Carbonite doesn't recognize only 4 or 5 fonts.
Why ?
The problem solved for me after I installed Ace2 (as I found somewhere the information that Carbonite uses it) and to be sure, I installed Ace3, too.
Please confirm if that does the trick also for you.
