You can start by telling us something about your system, your OS, and your version of AE. Don't forget to tell us about your project. It's as difficult for me to answer your question as it would be for you to answer this question. Why is it doing this when I do that with this?
Please let me know if you can figure out what that and this is without further explanation.
As Rick says, we need to know a lot more if we're going to help you. Please provide answers to the questions listed here: "FAQ: What information should I provide when asking a question on this forum?"
My OS is AMD FX(tm)-9320 Eight-Core Processor with 16 GB RAM and a 64-Bit Operating System. Im using CS6 and it is screen recorded video using fraps to record. This just started happening, where it froze. Whenever I click add to render que then click output to or render it freezes, I have to open task manager to close it or else it will just stay that way.
