Preview won't playback more than 2 secs
I've been using After Effects for simple animations for a few months now and not had any problems but recently I started using after effects through premiere pro to create transitions on videos and now when I try to create animations my projects will not preview more than 2 seconds and I keep receiving the Cached Preview needs 2 or more frames to playback error message. I already tried purging cache memory and several other techniques I've seen online to fix this but nothing seems to work. I feel as if something is corrupted from using after effects within premiere because even very simple animations will not preview now.
Let me know if you have any ideas of what could have gone wrong or what I could do to fix it. I'm thinking about upgrading my RAM from 16GB to 32GB but it used to run fine and my projects are small so I don't think thats the problem.
