Playback has frozen in Premiere Pro CS6. I am running a 1080p timeline and it appeared to start when I added some after effects renders to my timeline. The playback head still runs through the timeline and audio plays normally but the video completely stops and cannot be viewed in real time.
I have plenty of memory and a very good graphics card running 64Bit Windows 7.
You may have to render, dude. Linked comps require this often.
