9.x = CS4.
To answer your question, no.
After Effects project files are not backwards-compatible.
Oh ok..Im new in AE btw..So is there a plugin that lets you open CS4 projects in CS3? or is there a way to open this file in CS3?..I dont Have CS4 btw
Welcome to After Effects, and as stated above, no.
You can not open files created with a newer version of After Effects in older versions of After Effects.
Yeah i know its just like opening a .docx in MS Word 2003..but they do have plugins that enables you to open a docx file in MS Word 2003..and that was my previous question if there is a plugin or a way to open the project file in CS3..anyways thnx for the help:)
Just to confirm: No, there isn't. This is a million times more complex than just loading a few text files and would be a major effort...
