I'm using Flash CS5.5, working with some graphics and using some classic textfields. But, one day I opened the fla and all the embedded textfields were blank. I changed it to other fonts and worked perfectly, but not the font I was using (Myriad Pro). It only works if I choose "Use device fonts". So, does it has to do with some cache or something? I've erased all the fonts, rebooted my computer, and again the same problem.
It's not a scripting problem, may be a bug in flash?
UPDATE: In fact none of the OpenType CFF are working in my Flash. How can I restore these fonts?
UPDATE 2: Does it has to do with the Windows XP updates of 13/12/12? Someone has another SO with the same problem?
