Been working on a project these past two days. Nothing over the top complicated in it. Animating text/solids with an audio bed.
However this morning, while loading up the project, it froze at 33%. Had to Force Quit, try again. Nothing. I've actually taken the project file, brought it to another computer, which opened fine, then saved it as a new project, then brought it back to my computer which only let it work for about another hour - until giving me another freeze while working in the project.
I tried resetting my preferences, Purged the memory, brought to the other computer to transfer into a new file again. No go. Keeps freezing at 33%. Please Help
We're gonna need a lot more information such as what your system specs are, what version of AE you're using, what effects you're using, etc.
What Michael said - more info. Could be anything from some CoDec in your footage that differs across systems to the usual graphics card and driver issues to something being bad with your MediaCache....
