I've had the same problem ... every couple of weeks, I'll be working on a mix and boom, the sound drops, then the program crashes. I close and reopen and re-load the project ... but it just does it again. If I change projects it will stay, but until I open a ticket and get help, that project keeps freezing. Tech fixes, then 2-4 weeks later, different project ...boom. Start all over. Have you figured it out?
