I've recently restarted to learn Spanish again, and I'm using my old Fluenz F2 but it won't run on my mac now. It gives me an error when I try to set it up, saying "PowerPC applications are no longer supported." If I supply the serial number for the disc set and my registration info, is it possible to get the new update or do I need to purchase F3? I've really loved using Fluenz and am looking forward to reviewing my Spanish with you. Thanks!
