I just upgrade my iMac with Mountain Lion OS, and after that my Flash CS6 doesn't load Open Sans font family. I mention that i have Creative Suite CS6, and all the others products are working properly (Photoshop, InDesign, Illustrator...all are seeing the Open Sans). Before the upgrade it works fine Flash too. I tried a solution from web, to empty the file called fontinfo.txt. I reinstalled the Flash CS6 product too, but same problem.
