Ok, I'm getting there guys. When I become a Pro, I will share the knowledge as well.
Here is my new problem:
When I do a RAM Preview in AE first of all it takes about 30-45 seconds to start. Is this normal? When it does start playing I can't hear any sound AND it doesn't play the whole composition. The status shows: "Playing from RAM: 121 of 10199 fps: 29.97 (real-time)" Is there a setting or something that I have to set to hear sound during my RAM Preview and for it to play the whole composition?
