A little more system info would help. Are you up to date? I'm running CC and CS6 and CC14 on four different Macs without any problems. What else is going on with your system? What does the activity monitor look like? What is running in the background?
Running the latest versions of both Premier and AE CC.
Many bugs, slow renders, not able to render multiple frames at ones, after moving a Premiere project to another drive frame interpolation clip settings are lost.
All problems that others are having and are posted here. Adobe support is useless.
Have not checked activity monitor, nothing is running in the background, trying to quit all apps and shut down but AE is stopping this from happening. have to force quit shut down the computer.
