I installed Master Collection CS6 on my Mac Pro tower 3,1 quad core, 16 GBs RAM. I set up a new video project in Premiere and all was going fine, loaded all assets, etc ... Next I was attempting to set up audio hardware for recording a narriation on a track. I was using a USB VoIP device. I could not arm a track for recording, so I figured audio hardware needed set up. My VoIP was already selected in Preferences>Audio Hardware once inspected, but I still could not arm a track. So, I tried Utilities>Midi Set Up>Aggregate Audio Devices to add my headset to Premiere Pro. Headset was in list but I could not add anything to premiere. Everything I checked automatically unchecked once selected.
Back to square one. So I unhooked my headset, went to Preferences>Audio Hardware and attempted to select a Built-in I/O device. Then, Premiere just crashed.
Everytime I try to open premiere it crashes. I rebooted, tried a different project, etc .... nothing!
