When you try to open a project, I jumped out the window After Effects error.the file you are Attempting to open was created with After Effects version 13.0 (Windows 64) and can not be opened with this version. See www.adobe.com/after effects for information on upgrading you like.
I emphasize that I'm working on AE CS 6 (Windows 64).
Can you please advise what is the problem?
Thank you very much
