Hi...hoping someone can help me here. I have MSv12 which was working fine until I downloaded an Avid DNxHD codec and Handbrake in order to try to a workflow process for upload to You Tube. When I loaded MS12 to check it had picked up the new codec the "Render As" function merely locked the application. I removed both new downloads....no change....I went to a system restor point that pre dated those downloads...no change. I de installed MSv12 and reloaded from discs.....no change. Rebooted and removed MS12....rebooted and reinstalled MS12...no change. What I have also noticed is that when I re install MS12 from the disc it does not appear in my Start/program list with the normal Icon...it now has a white icon with 6 small icons on it...too small to see more. Everything else on the application appears to work and all other apps on my PC appear to work OK. Any ideas?
